Description

The SenTix® HWD pH special electrode with its ground joint diaphragm, high-quality glass shaft and 170 mm length is particularly suitable for low-ion media, aqueous and partially aqueous samples in the laboratory and where pH measurement with standard electrodes fails due to the composition or nature of the sample. The spherical shape of the membrane offers constant measurement quality and low resistance due to the large surface area and with refillable 3 mol/l KCl liquid electrolyte, the electrode offers fast response times. The SenTix® HWD has an NTC 30 kOhm temperature sensor.

The SenTix® HWD is particularly suitable for the following applications:

Chemical:	Industrial:
Emulsions/suspensions Sulfide-containing liquids	Cooling water, dyeing solutions, electroplating baths
Water & Environmental:	Beverages:
Boiler feed water, condensate, distilled water, demineralized water Saline solutions Lake water, surface water, sea water Rain water Soil extract	Beer, soda/lemonade Fruit juice, vegetable juice, wine Mineral water Milk
Food:	Cosmetics & Cleanings:
Coffee extract Vinegar Yogurt, quark	Hair color Mouthwash Shampoo Household cleaners
	Pharma, Medical, Bio:
	Enzyme solutions, gastric juice, infusion solutions, protein-containing liquids, serum, tris buffer solutions, urine
