ISFET Waterproof pH Meters
 |
Ion specific field effect transistor (ISFET) uses a silicon chip pH Sensor |
 |
Sensor stores dry and needs little maintenance |
|
Fast response time |
|
These compact, waterproof pH meters can measure samples as small as one drop. The virtually unbreakable sensor eliminates breakage problems associated with fragile glass pH sensors. Advanced model offers three-point calibration and auto-buffer recognition.
What's included: calibrating buffers, case, batteries, and instruction manual.
