型号：24200 |
Hand-Held
ISFET pH Meter
|
Model
No.'s 24200 |
|
DeltaTRAK's new non-glass ISFET(Ion
Sensitive Field Effect Transistor) Hand-Held pH meter does away
with all the drawbacks of a glass pH meter and lasts 3 times
longer than glass. The non-glass, rugged, completely submersible
probe stores dry and requires no-fill solutions or routine maintenance.
|
 |
The combination pH and temperature probe features a high
temperature automatic temperature compensation (ATC), lightning
fast readings and set up time for a new or dry probe is just
10 minutes. The only cleaning required is brushing the tip
with a toothbrush.
Measuring pH for semi-solids, slurries and liquids is now
fast, easy and accurate to ±0.01 with ISFET technology. The
advanced Model 24201 features a data logging capability.
