MS1

Conductivity meter

Description

Measures the conductivity of a liquid, degree of purity is established.
The amount of dissolved solids in boiler water can be directly related to its conductivity level.
Checks boiler water.
Checks feedwater TDS levels.
Calibrates control instrumentation.

The Spirax Sarco MS1 is a battery powered conductivity meter designed for use with liquids. It is particularly suitable for measuring the conductivity of boiler water, feedwater, or condensate samples in order to estimate the level of Total Dissolved Solids, or TDS.
The instrument is fitted with a permanently wired carbon electrode sensor with integral temperature sensor.
A plug-in extension lead is also provided to allow ac resistance measurements to be made on installed conductivity probes in order to check their condition.
Calibration to a master instrument or standard solution is possible using the adjustment screw on the side of the case.
The instrument is supplied in a protective wallet.

Principal features:
– Automatic temperature compensation
– Wide selectable range
– Automatic switch-off

Limiting conditions

Maximum recommended sensor operating temperature 45 °C.
