Multi-parameter laboratory controller

Measures pH, redox, ion concentrations, conductivity and dissolved gases

The LM 3000 multi-parameter laboratory controller has a modular bus structure; it provides excellent functionality, maximum operational reliability, outstanding ease of use, and a wide range of customized configuration options.

The LM 3000 offers a complete system solution whenever several electrochemical quality parameters need to be detected on-line in a laboratory setting, and where these measurements need to be transmitted and evaluated very reliably.

The main functional units of the LM 3000 multi-
parameter laboratory measurement system are:

The LM 3000 multi-parameter laboratory base unit with power supply, touchscreen display (backlit 5.7”, 320 x 240 pixels, with full-text menu navigation)  4 potential-free (floating) relay outputs, data logger and logbook, various digital interfaces such as RS232, USB and Ethernet

• Internal measuring modules (max. 4)
• PC-based visualization program
• Sensors
• Optional sampler, up to 72 samples depending on type (e.g. TW Alpha plus)
• Optional Titronic 500 dosage system
• Optional stirrer

Classic plug-in tensiometer

A tensiometer is used to measure suction tension. The porous cell of the tensiometer uses capillary action to transport water outwards into the drier soil. A negative pressure is then created within the closed pipe. This negative... ...more Topseller
