The PH8500-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 PH8500-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. Furthermore, the meter has a memory function and GLP data management with storage space for up to 500 memory groups. It can be connected to a PC or laptop via USB to either read out the memory groups or perform real-time storage.

Electrode

LabSen electrochemical sensors are premium pH electrodes with manufacturing technology and key components from Switzerland. The LabSen553 pointed pH electrode has a spear membrane that can easily penetrate solid or semi-solid medium. The electrode is suitable for pH measurement of fruits, vegetables and soil samples.

This electrode has the following properties:

Solid PVC case, provides stronger protection.
Blue gel electrolyte, does not flow and does not cause air bubbles.
Maintenance-free polymer electrolyte, hole diaphragm structure.
Durable reference system, better stability and lifetime.
