Description 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. MS1 Conductivity Meter MS1 Conductivity Meter
