AI316 Premium Series PC60 5-in-1 Waterproof pH/EC (Conductivity) /TDS (ppm) /Salinity (ppt) /Temp. Multi-Parameter Pocket Tester Kit

I’ve been using the Apera PC60 for a few weeks now, and it has significantly improved my ability to manage my indoor hydroponic garden. I’m growing vegetables for my guinea pigs, and providing fresh, high-quality greens is a vital part of their diet. I chose this model because I wanted a reliable tester that could measure both EC and pH. While combining both functions into one device does create a single point of failure, I trusted Apera’s reputation for quality and accuracy. I previously used inexpensive $10–20 testers for pH and TDS, but they were inaccurate and lacked calibration support. I also prefer working with the raw EC values rather than calculated TDS, so the PC60’s direct EC readings were a big plus. Since switching to the PC60, I’ve been able to dial in both my nutrient concentration and pH with confidence. My plants are clearly doing great, and I’m optimistic about achieving higher yields. A few tips and lessons I’ve learned that might help others: • Calibration for RO Water Users: If you’re using reverse osmosis (RO) water, be sure to purchase 84 μS calibration fluid. The included 1,413 μS and 12,880 μS (12.88 mS) solutions don’t cover the low EC range of RO water. Without 84 μS fluid, my tester initially showed about 600 μS for pure RO water. After a proper three-point calibration, it correctly read near 0 μS. • pH Agitation Tip: When measuring pH, gently agitate the water by moving the tester in small circles. This helps the reading stabilize much faster—around 15 seconds compared to several minutes if left still. • Beakers Make Life Easier: Having a few small beakers makes sampling and rinsing more efficient, especially when pulling water from a larger reservoir. • Track Your Calibrations: I keep a notecard in the carrying case to record the date of my last calibration and how many times I’ve used each solution. Most calibration fluids can be reused up to five times before they should be discarded. • Proper Storage Tip: Unlike some pH meters, the PC60 probe shouldn’t be stored in 3M KCl unless it’s being stored for a long period or has dried out. For regular use, just add a few drops of clean water (distilled or tap) to the cap to keep the probe hydrated. Avoid soaking it in KCl long-term, as it may shorten the lifespan of the sensor. All in all, the Apera PC60 is a fantastic investment if you’re serious about hydroponics. It’s accurate, convenient, and far more reliable than cheaper alternatives. Highly recommended.

An absolute must have tool for all your PH, EC, TDS, Salinity, and Temp. Easy multipoint calibration, extremely accurate and holds calibration well over extended time periods. With the added protection for the pH bulb I expect this tool to last many years with proper care.

Excellent device and a must have for testing and maintaining aquarium water. I check the PH in the morning and evening of my planted tank to monitor that my buffer is maintaining a stable PH. Far, Far, Far, more accurate than any test strips. Being able to quickly check 5 water parameters is very convenient.

The Apera Instruments AI316 PC60 is an exceptionally versatile and reliable tool. It accurately measures pH, conductivity, TDS, salinity, and temperature quickly and simultaneously, making it ideal for both professional and discerning hobbyists. The multiparameter probe is easy to replace, and calibration is intuitive. It is undoubtedly an excellent investment for anyone requiring accurate measurements in the field or laboratory.

NOT WATERPROOF!!! I have only had this for a month, and it has been working as it should. I accidentally dropped in a one of my file gallon hydroponic buckets. I quickly retrieved it and rinsed it off and dried it. I start testing again and it was not working. I opened it up and it was full of water. After contacting customer service they said dry it out and let it set 24 hours. It still fails to work. All it will do is read - 2.00 on PH and calibration will not work. When I told their support team it is was still not working here is their response. Don't waste your money the cheaper Chinese clone is just as accurate and is waterproof. "According to our warranty policy, coverage applies only to manufacturing or material defects present at the time of delivery. Any damage occurring after the product has been received—such as water or accidental damage—is outside the scope of the warranty." UPDATE: Apera did come back and replace the unit. I appreciate that and believe it was the right thing to do. The moral of the story is to make sure you use a lanyard when testing, as it does not appear to be waterproof if totally submerged.

The Apera Instruments PC60 is a great 5 in 1 pocket tester. The meter is easy to use. It gives quick, accurate, and reliable readings. The ability to replace the probe will be perfect for extending the life of the meter. This also gives you the possibility to test the pH of other media other than liquid (with purchase of other style replace probes). You also can have peace of mind knowing that the meter is IP67 waterproof (it will sink if dropped in water). A few notes for use. If you are testing liquid that is being aerated make sure you are testing a sample without bubbles moving around the probe, otherwise you may get erratic readings. Conductivity switches units from µs to ms above 1999 µs. TDS switches units from ppm to ppt above 999 ppm.

ACTUALIZACIÓN: Después de 2 años de uso, sigue funcionando perfectamente. Lo único que no me gusta es que Amazon no tenga disponibles las puntas necesarias para el reemplazo. Buscando por otros sitios, incluída la web del fabricante, los gastos de envío son desorbitados. Al final, cuando la sonda deje de funcionar bien, tocará comprar todo el aparato de nuevo. No sólo es un gasto mayor, sino que tampoco le hace ningún favor al medioambiente. ------------------------------------------------------------------ Si bien aquí en Amazon España se lleva casi 5 estrellas este medidor (en concreto en mi caso es el PC60 Premium de Apera) en otros países parece que hay ciertas quejas. Supongo que porque sólo escriben los que han tenido mala suerte con algún medidor, o lo que creo más probable, es gente que ni siquiera se lee las instrucciones para saber cómo usarlo y sobre todo como conservarlo correctamente. Lo he comprado fundamentalmente para poder controlar los parámetros de un acuario y por lo pronto no defrauda, todo lo contrario. Sobre todo el hecho de poder cambiar el sensor ("la punta") por más o menos la mitad de lo que sale el producto entero cuando sea necesario en un futuro resulta una gran ventaja. Es cierto que hay juegos de medidores de pH y TDS por unos 30€, que viene a ser la cuarta parte de lo que cuesta este, pero a diferencia de este ni compensan temperatura, ni son waterproof, ni se puede cambiar la sonda y un largo etc.

Ne ho provati tanti, ma questo è l'unico strumento che restituisce valori precisi e soprattutto ripetitivi, cosa che non è assolutamente scontata. Apera pc60 è davvero un ottimo strumento, fornito con tutti i liquidi neccessari per la sua taratura e mantenimento dell'elettrodo quando non si usa. Lo strumento permette la taratura su 3 punti, ph 4, ph 7 e ph 10, questo assicura una precisione assoluta. Misura tutto e lo fa bene! È caro senza nessun dubbio, ma il prodotto è davvero ottimo. Consiglio l'acquisto

Buen producto y muy buena precisión. Lo recomiendo.

Read that lots of people were saying the conductivity probe would stop working after weeks to months of use. This did make me hesitate buying the product however I thought if it fails, I will just return it. 2 weeks in, I start getting the 0.00 readings like i've read so much about but the PH worked fine.. Im not going to lie I thought it was time to send it back but I thought to myself. I wonder if it's running out of battery. The batteries this instrument is supplied with are of extreme poor quality. The buy a pack of 100 for a pound type.. SWAP THE BLOODY BATTERYS! The testers are fine, keep the probes moist and follow the guidelines. For god sake people, if something that runs of batteries starts to act faulty, don't start kicking off at the manufacturer before making this simple check. To me this is common sense.

J'utilise cette appareil pour l'eau de mon aquarium. L'appareil est arrivé propre, sonde bien hydraté, pas de fuite de produit dans la valise. Valise de bonne qualité. L'appareil paraît de très bonne qualité. Je l'ai utilisé pour l'eau de mon aquarium et les résultats sont précis et tout à fait cohérent par rapport à mes résultats habituellement mesuré avec des tests en gouttelettes JBL. Ce serait vraiment un plus d'avoir une notice en français quand le produit est destiné à la livraison en France. Ou bien une vidéo en français accessible sur internet.
