Cole-Parmer recently introduced Oakton Waterproof Multiparameter Testr 35-series Meters. This is a convenient pocket-sized meter that measures pH, conductivity, TDS, salinity, and temperature.

The versatile OAKTON waterproof multiparameter Testr 35-series meters is perfect for water, wastewater, laboratory, and plant use.These pocket-sized meters have long-life pH electrodes and stainless steel conductivity sensors for a wider range of sample compatibility. The easy-to-replace sensor modules helps you save money, allowing you to reuse the meter body.

It's convenient, fast, and simple-just dip, measure, and can scan through up to five parameters with the push of a button. There is no complicated operating procedures and no need to change sensors for different measurements. These meters offer multiple calibration options-choose single or multipoint, automatic or manual.Conductivity or TDS can be measured more accurately at varying temperatures with an adjustable temperature coefficient feature. Auto-ranging feature also makes it more convenient for users with applications across broad measurement ranges. The unique sensor design provides faster ATC response and faster readings.
