pH Meter GMH 5550

Water-resistant pH meter with data logger / serial interface / analog output / large dual display / calibration function / robust silicone protective cover / IP 67

As a waterproof pH meter, the GMH5550 is ideal for use in very humid environmental conditions. Thanks to the robust ABS housing, the waterproof pH meter can be used even in the most unfavorable conditions. The especially large display of the waterproof pH meter shows the measurement values according to the connected probe. Calibration of 1, 2, or 3 points, as well as automatic temperature compensation, ensure high accuracy of the waterproof pH meter, even in cases of highly fluctuating measurement temperatures. All this allows for quick and reliable measurement with the waterproof pH meter. Additionally, the waterproof pH meter can determine pH value, temperature, or REDOX potential (ORP).

- Manual temperature compensation.

- High resolution

- Water resistant according to IP 67

- 9 V battery

- Compact and robust ABS housing

- Optional calibration set
