John Morris Scientific are pleased to introduce Cole Parmer’s Oakton Testr 35 series multiparameter meter.

The pocket-sized Testr 35 is waterproof making it ideal for water, wastewater, laboratory, and plant use.

The Testr 35 has a long-life pH electrode and stainless steel conductivity sensors for a wider range of sample compatibility. Sensor modules are easy to replace, therefore allowing you to re use the meter body. The Testr 35 is fast, and easy to use -  just dip, measure, and scan through up to five parameters with the push of a button. There are no complicated operating procedures and no need to change sensors for different measurements.

The Testr 35 offers multiple calibration options—choose between single or multipoint and automatic or manual. Measure conductivity or TDS more accurately at varying temperatures with an adjustable temperature coefficient feature. An auto-ranging feature makes it more convenient for users with applications across broad measurement ranges. The unique sensor design provides faster ATC response and faster readings.
