Waterproof Microvolume Back light 2pt_cal

 

The only pocket meter that directly measures nitrate ion and nirate-nitrogen concentrations in 0.3ml sample (or 0.05ml sample with sampling sheet B). Unique sensor allows measurement of viscous liquids, solids, and even powder samples. No need for a beaker to calibrate your meter or measure a sample. Just place few drops of the standard or sample onto the flat sensor. This procedure saves you time and prevents wasting your precious sample.

  • Minimum sample volume: 0.3ml (0.05ml with sampling sheet B)
  • Up to 2 calibration points
  • Auto standard recognition
  • Changeable high and low calibration values
  • Multiplication compensation: 0.01 to 9.90
  • Temperature and mV display
  • Temperature calibration: 5 to 40.0 ºC
  • Auto hold / auto stable measurement
  • Auto power off: 30 mins.
  • Low battery indicator
  • IP67 Rating dust & waterproof
  • Replaceable sensor
  • 400 Hours battery life: continuous use without backlight

Nitrate Measurement in Hybrid Sudangrass and Pearl Millet Hays
Determining the nitrate concentrations of sudangrass and pearl millet before feeding them to livestock prevents nitrate toxicity. Plant sap testing with LAQUAtwin B-743 nitrate ion meter offers fast and accurate nitrate in-field analysis. Generally, the maximum nitrate concentrations considered safe for all cattle are 820 ppm and 700 ppm for sudangrass sap and pearl millet sap, respectively.
