Ion Science Receives Independent Verification for Best Performing PID
The Ion Science PhoCheck+ has received independent verification as the best performing photoionisation detector (PID) by the state of Maine Department of Environmental Protection (ME DEP). Subsequent to a stringent testing and selection process between competing PID technologies, the ME DEP has standardised the Ion Science PhoCheck+ 3000 for use in all their underground storage tanks, emergency response and air monitoring applications.
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.

Ion Science Launch New Transportable Hydrogen Flux Monitor
Ion Science is pleased to announce the launch of the newly developed, battery operated Hydrosteel 7000 Transportable for the continuous monitoring of hydrogen flux. The new instrument provides non- intrusive, continuous monitoring of hydrogen flux, wherever, and whenever it is needed, to identify and confirm control of corrosion and hydrogen crack risk.
Simple to install and maintain, the battery powered corrosion monitor requires no wiring, with each battery charge lasting up to nine months. Hydrosteel 7000 Transportable is useable on hot, cold, curved and flat surfaces, and benefits from easy data manipulation.

Fence Electrode Technology or Humidity
Compensation?
A recent evaluation was conducted to compare a PID cell incorporating Fence Electrode Technology against one equipped with Humidity Compensation. Test results prove that an Ion Science PID with Fence Electrode Technology is twice as accurate, more stable and faster than a PID with Humidity Compensation.
The published data shows that when subjected to high humidity, an Ion Science PID with Fence Electrode Technology is much less subject to drift, while responding and clearing out faster, resulting in much fewer non-reports. The comparison bet- ween the two leading PID instruments clearly shows that the Ion Science PID technology performs far better than its closest competitor.
