Senmatic's Mesur hand instrument for measuring EC & pH

Mesur Hand Instrument

Combined EC, pH and temperature measuring instrument

Mesur is a combined measuring instrument for EC, pH and temperature. This conveniently-sized unit was developed for daily use in greenhouses, nurseries, turf fields, and other outdoor applications. Mesur is an updated version of the well-known Senmatic EC and pH hand instruments of which more than 10,000 pieces have been sold.

Simple operation and unique design
Mesur has the same distinguished and timeless design as the Senmatic system 9000 series. It has six operational buttons that operate with one click. This development enhances performance over the older models that require continuous manual depression to obtain a reading. The buttons are placed so that the unit can be operated with one hand on the control panel at a time.

Complete delivery
Control liquids for calibration of EC and pH, if applicable, are enclosed with each shipment of Mesur. Additional calibration liquids are available from Senmatic. Mesur is delivered in a practical and durable hard plastic case with sufcient space for all control liquids and sensors. The case is well suited for transport throughout the nursery or feld.

Mesur is delivered in two models
Our deluxe model has EC, pH, and temperature measuring facilities. Also available is a unit measuring EC and temperature alone.
