The PH850-SL 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 specially designed to make direct soil pH measurements quickly and easily. The included LabSen® 553 pH electrode has a pointed & stable glass membrane and a solid polymer electrolyte, so it can be easily inserted into the ground for measurement without causing damage or clogging the diaphragm. The electrode has an integrated temperature sensor, which enables automatic temperature compensation (ATC). The PH850-SL is protected by a silicone cover and is waterproof and dustproof (IP57), making it particularly well suited for field use, even in harsh environments.
- Equipped with the LabSen® 553 pH electrode with tip for direct soil measurements
- Silicone case provides safe & firm grip and protects from shocks
- Waterproof and dustproof (IP57) for use in harsh environments
- Fold-out stand for convenient indoor operation
- Quick and easy 1- to 3-point calibration
- Large, illuminated LCD simultaneously displays conductivity value and temperature, as well as additional measurement and calibration information
- Self-diagnosis supports calibration or troubleshooting
The meter is RoHS and EC certified and has a 3 year warranty (6 months on the electrode).
Electrode
The LabSen® 553 from Apera Instruments is a pH insertion electrode with integrated temperature sensor and is manufactured using proprietary Swiss sensor technology and materials. Reinforced by a PVC housing, the pointed electrode can be used to directly test semi-solid to solid samples such as soil, fruits, vegetables, etc.
LabSen S-Type Pointed Glass Diaphragm – Thanks to the low-resistance and rugged pointed glass diaphragm, the electrode delivers fully stabilized readings in 15 to 30 seconds, yet is up to 10 times more robust than conventional products, significantly reducing the likelihood of the electrode breaking during impact or when penetrating samples.
Polymer electrolyte with hole diaphragm structure – Allows direct contact with test samples without clogging the diaphragm structure. The electrolyte does not need to be refilled.
Long-life reference system – The LabSen 553 pH electrode uses a long-life reference system consisting of a glass tube, AgCl and a reference silver wire. The top of the slim glass tube is filled with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference electrode and extends the life of the electrode.
