Answered Questions

Question: Can this be used to test semi-solids?
Answer: Yes

Question: Is this one suitable for continuous monitoring of pH and conductivity for a long-term?
Answer: Each test is a single procedure you must follow so you can spot check but not continuous.

Question: Does the app work without the cloud, ergo can you use it when there is no cellular network?
Answer: The device works with the app connected by bluetooth only. No clouds needed! The device will also work independently without the phone as well.

Question: How many ml calibration liquids in each bottle?
Answer: For the calibration liquid comes with the kit, it is about 50ml in each bottle.

Question: Has anyone used this to test sourdough starter pH?
Answer: The standard Apera pH meter was used to test a sourdough starter as follows: 2 grams of active sourdough starter was mixed into 18 grams (milliliters) distilled water and the pH measured on the water. The pH found was 3.8. When measuring pH of a semi-solid such as bread dough, there may not be enough moisture to get an accurate pH. There must be sufficient water to permit ion mobility. A suitably wet sourdough starter, of the consistency of pancake batter, would be measurable with a pH electrode.

Question: Do I need to use buffer powder to test pH?
Answer: No you just need buffer solution to calibrate the meter. No buffer is required during actual pH testing.

Question: Does this measure the salt level?
Answer: PC60-Z also measures Salinity. Its salinity range is 0-10.0 ppt (parts per thousand).

Question: Does this come in a case?
Answer: Yes, case in included.

Question: Can I use this meter to test the pH of homemade syrups? Or do I need to buy an attachment?
Answer: PH60S-Z is suitable for testing the pH of semi-solid/solid samples. Additional sensors would not be needed for measuring syrups.

Question: What is the TDS range in ppm?
Answer: 0-10,000 ppm

Question: Can you replace just the probe?
Answer: Yes, the probe can be found here.

Question: Does it float?
Answer: No, it’s meant to be immersed in water.

Question: Does the product have a calibration or quality certificate?
Answer: Yes, the quality certificate is included in the package.

Question: Can this be mounted to be submerged constantly for around the clock monitoring?
Answer: As far as I know, the answer is no. If for no other reason that it’s battery saving feature would shut itself down.

Question: How often does this need to be calibrated? And what is the process for calibration?
Answer: I calibrate mine weekly, sometimes more frequently. The calibration process is very simple and is no different than other pH probes.

Question: Can I use this for sushi rice?
Answer: For sushi rice, our pH60S-Z Bluetooth smart pH tester with a spear probe would be better. Please view here.
