The ME DEP evaluated the PhoCheck+ 3000 against its closest competitor for ease of use, speed, repeatability and linearity between concentrations. Firm evidence showed the Ion Science PID to give more consistent, clearer readings and was faster to read results.
To strengthen the ME DEP’s findings, a subsequent trial was conducted to compare a PID cell incorporating Fence Electrode Technology against one equipped with Humidity Compensation. The published data proves that an Ion Science PID with Fence Electrode Technology is twice as accurate, more stable and faster than a PID with Humidity Compensation.
The data shows that when operating in changing or high humidity environments, a Fence Electrode PID is much less subject to drift, while responding and clearing out faster, resulting in much fewer non-reports.
