Portable Multi-parameter Water Analyzer
Short Description
The Lohand LH-M900 is a portable multi-parameter water analyzer based on spectrophotometry, with four wavelengths (420/470/520/620 nm) and more than 20 test parameters including chlorine, ammonia nitrogen, nitrite, phosphate and heavy metals, configurable to your needs. IP65 protection, an OLED display, 5,000+ record storage and USB or battery power make it ideal for wastewater discharge, aquaculture, surface water and laboratory testing.
Portable Multi-parameter Water Analyzer LH-M900
The Lohand LH-M900 is a portable multi-parameter water analyzer based on spectrophotometry, supporting wavelengths of 420, 470, 520 and 620 nm. It tests more than 20 parameters with a simple, fast and highly sensitive method. An imported sensor and an advanced optical system with an extended measuring range reduce the time spent on sample dilution. Small, light and easy to carry, it suits field work, and the test parameters can be configured to your application.
