Apera PH850-WW Portable pH Meter Kit
Designed for professional pH measurement of wastewater, emulsions, effluents, and other turbid water solutions containing sulfides and proteins with the LabSen 333 POM-body 3-in-1 pH/Temperature electrode. Also works well with general water solutions.
Key Features
- Equipped with the Swiss LabSen 333 POM 3-in-1 pH/Temperature electrode, designed for professional wastewater pH measurement
- Automatic temperature compensation
- Intelligent functions: self-diagnosis of out-of-range values and electrode invalidation, automatic calibration, electrode slope display, auto power-off, and easy parameter setting
- Easy 1-3 point pH calibration, automatically recognizing pH standards of 1.68, 4.00, 7.00, 10.01, and 12.45
- Large LCD display with a stability icon, icons for finished calibrations, and simultaneous temperature display
- Rugged structure design: IP57 waterproof rating, with a soft silicone case that gives a firm and comfortable grip
- Powered by 3 AA batteries or DC 5V (USB port)
Built Tough
The IP57 water-resistant structure makes the meter ideal for use in harsh environments. The rubber sleeve protects the instrument from general impact and gives you a firm grip.
LabSen 333 POM 3-in-1 pH/Temperature Electrode
Built with proprietary sensor technology and premium materials from Switzerland, the LabSen 333 POM-body 3-in-1 pH/Temperature electrode is designed for professional measurement of wastewater, emulsions, effluents, and other turbid water solutions containing sulfides and proteins.
Specialized Electrolyte
Apera's proprietary blue gel inner solution does not flow at all, which means it will never generate air bubbles. The electrode can work well even when held upside-down. It is not only more convenient to use, but also improves measurement accuracy by eliminating heat convection in the inner glass membrane.
Open Junction + POM Body
The POM electrode body is highly resistant to corrosion, ideal for use in harsh environments. The open junction ensures full contact with solutions while eliminating junction clogs. No need for electrolyte refill.
Long-Life Reference System
Composed of a glass tube, AgCl, and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference system and extends the service life of the electrode.
