Beschreibung
The PH850-HF from Apera Instruments is a handy and easy-to-use meter for the determination of pH, ORP (electrode sold separately e.g. 301Pt-C) and temperature. It is ideal for making precise and reliable measurements of solutions with a strongly acidic character and hydrofluoric acid. The LabSen® 831 pH electrode included in the scope of delivery is equipped with a special HF glass membrane, which is extremely resistant to HF corrosion and thus significantly extends the service life of the electrode. An MP500 temperature sensor is included in the set for temperature measurement. The PH850-HF is protected by a silicone cover and is waterproof and dustproof (IP57), making it particularly well suited for field use, even in harsh environments.
