It is also compatible with 3 other pH probes and an ORP probe (sold separately) for different applications such as solid samples and surface test. IP67 waterproof and dustproof, floats on water so no need to worry if it falls into water by accident. Up to 1000 hours' continuous operation powered by AAA batteries (with low power warning and auto power off in 8 min if no operation).

NOTES: The instrument will NOT give accurate or stable readings for distilled or deionized water's pH testing. To measure distilled or deionized water’s pH, users need to use a specialized pH meter like Apera SX811-PW. Do NOT store the probe in distilled water or deionized water because they will cause damage to the pH probe. Only use distilled or deionized water for rinsing the pH probe.

## Questions & Answers

**Q: For egular maintanance, does the device /probe must be kept inside a solution or can it be kept inside its case dry?**
A: The latest online instruction manual (version 7.7) says this about storing the PH60 probe: 

7 Probe Storage 

7.1 Under regular usage (daily or weekly use), make sure the probe cap is wet, and tightly close the cap with the O-ring. 

7.2 For long-term storage (you are not going to use the product for a while), add 3M KCL soaking solution to the Fill line in the probe cap and store the probe in it. Close on the probe cap tightly with the O-ring. 

7.3 If you find white crystals inside or outside the probe cap, it is perfectly normal. It is the 3M KCL soaking solution that crystalizes over time by its nature. Just rinse them off and add in new soaking solution. This chemical is not poisonous nor dangerous, and the probe’s performance will not be affected at all. 

7.4 NEVER store the probe in pure water like tap, RO, distilled, or deionized water as they could damage the pH probe. Pure water is only for rinsing the probe.

**Q: Would this work for chemistry experiments (done as part of a homeschool chemistry course)?**
A: Yes, but advanced warning, we recommend keeping the ph measure above ph of 2 and below a ph of 12 as ph measures beyond those points will shorten the life of the sensor and is considered improper use and voids the warranty. 

It may be wise to check in advance if the chemistry course will have the student delving into substances more acidic than lemon juice like HCL, or more alkaline than hand soap. Be sure to have distilled water to rinse all substances away from the probe when testing.

**Q: Looked up the replacement probes. Freaking 35-50 bucks on average. Could just buy a whole new pen for that much? Any cheap replacment probes?**
A: Just replaced my probe on my PH60 after 2.5 years use.  Got it in two days, for $28.

**Q: Does this check PPM ?**
A: No, that would be our EC60 and PC60 that will do PPM under the measurement for Total Dissolved Solids (TDS). PH60 does only PH and mV for an ORP probe sold separately.
