Model pH 200 pH/mV/Temp Meter
Advantages
- pH / redox measurement and temperature measurement (Pt1000 or NTC 30kOhm)
- Automatic temperature compensation (ATC)
- Auto Hold function
- Internal memory for 20 data sets
- Automatic buffer recognition with Tintometer standard or DIN or individual buffer
- 1, 2 and 3 point calibration
- Low battery and battery change indicator
- Sensor evaluation in the display based on the calibration result (from 10 to 100%)
- Battery operation period up to 15000 hours
- Shock-absorbing rubber protective armouring
- Waterproof
The Series 200 Electrochemistry instruments are rugged, high performance handheld meters that are specifically designed for use in both the laboratory and the field.
The meters come standard with the following features:
- Waterproof housing with built-in storage compartment for probes.
- A built-in support arm can be flipped up to suspend the meter on nearby objects, such as pipes or branches.
- A simple user interface for easy meter operation both outdoors and in the laboratory.
- The automatic Hold function which “freezes” stable measuring data in the display and indicates the presence of reliable and reproducible results.
- The internal memory allows storage of 20 data sets to facilitate subsequent evaluation.
- The integral automatic switch-off feature, varying from 1 to 120 minutes, to preserve the battery life of the units.
The power consumption of all three units has been optimized. As a result, the 4 x 1.5 V integrated batteries have an operating life of up to 15,000 hours, depending on the version.
