LAQUAtwin-NO3-11 Nitrate Meter

Range and sample types

Readings go up to 9900 ppm, so high concentrations can be measured without dilution, and no reagents are needed. Solid samples go straight onto the sensor, the electrode can also be dipped into a liquid like a conventional nitrate meter, and absorbent sampling sheets allow micro samples from 50 μl.

Features

• Minimum sample volume: 0.3ml (0.05ml with sampling sheet B)
• Measuring range: 6 to 9900 ppm (0.1 to 160 mmol/l)
• Up to 2 calibration points, with automatic recognition of the 150 and 2000 ppm standards
• High and low calibration values can be changed
• Multiplication compensation: 0.01 to 9.90
• Shows nitrate, mV and temperature
• Temperature calibration: 5 to 40.0 °C
• Automatic temperature compensation
• Auto hold / auto stable measurement
• Auto power off after 30 mins.
• Low battery indicator
• Dust and waterproof to IP67
• Replaceable sensor
• Battery life of 400 hours in continuous use without backlight
• Material: ABS epoxy
• Display: custom monochrome digital LCD with backlight
• Operating conditions: 5 to 40 °C, relative humidity of 85% or less
• Warranty: 2 years for the meter, 6 months for the sensor
• Supplied in a handy carrying case with 150 ppm and 2000 ppm calibration solutions (14 ml each), CR2032 batteries (2), 1 syringe, instruction manual, quick guide and B sampling sheets

Typical applications

• Soil analysis (nutrient concentration in soil)
• Plant sap analysis (fertilization efficiency and crop nutrition)
• Food analysis (fish, meat, vegetables...)
• River water quality assessment
• Drinking water, fish tanks, etc.
