Senmatic's Mesur hand instrument for measuring EC & pH

Mesur Hand Instrument

Combined EC, pH and temperature measuring instrument

Measurement is a combined EC, pH and temperature measuring instrument in pocket format. Measurement is a further development of our well-known EC and pH hand instruments, and ensures an accurate measurement of EC and pH. The correct EC and pH values are essential to achieve the absolutely optimal growth conditions for flowers and vegetables.

Simple operation and unique design
Mesur has our well known distinguished and timeless design, and it has six operational buttons that operate with one click. The buttons are placed so that the unit can be operated with one hand on the control panel at a time. When a button is suppressed, Mesur will be powered for operation. If the unit is idle for more than one minute, the unit will turn off automatically to save battery power.

Mesur reliably shows conditions of low battery voltage, alerting when its battery must be replaced. This unit is a durable instrument built to withstand a humid environment. It is suited for normal daily use in the greenhouse, nursery, or outdoor climate.

EC values are normally read to one decimal point. Mesur, however, also has the possibility to obtain readings to two decimal points for EC readings lower than 2.5 mS.

What's in it for you?

  • Simple one hand operation and unique design

  • Temperature measurement

  • Exact pH and EC measurement

  • EC readings are temperature-compensated

  • Built-in memory to store the most recent values

  • Developed for measuring under difficult conditions

  • Compensates for the temperature dependence of the pH sensor

  • Complete delivery with control liquids

  • Available in two models - both well suited for transport

Mesur has a built-in memory to store the most recent EC, pH, and temperature values. This is especially practical when measuring under difficult conditions.

Temperature compensation
EC readings from Mesur are temperature-compensated. The unit accounts for the influence of solution temperature on the EC value and this is always shown/converted into the reference temperature. The EC value can be compared with previous measurements.

The pH sensor's temperature dependence
Mesur compensates for the temperature dependence of the pH sensor. The pH measuring is therefore more exact with Mesur than with ordinary pH meters.

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