Nitrachek Reflectometer
Eijkelkamp 18.40 Nitrachek Reflectometer

Product Features
  • A pocket size digital measuring instrument.
  • Eijkelkamp 18.40 Nitrachek Reflectometer for a simple and quick determination in the field of the nitrate content in water or in a watery extract of soil or crop.
  • Based on read-out of nitrate test strips. After a test strip is held in the solution it is placed in the optical read-out apparatus.
  • Up to 20 measuring sets with date/ time indication.
  • Measuring range of 5 - 500 ppm (mg/l) nitrate.
  • Accuracy of 1 mg/l.
  • The instrument is supplied including case, test strips, calibration solution and accessories.

pH Field Analysis Set
Eijkelkamp 18.44 pH Field Analysis Set

Product Features
  • Eijkelkamp 18.44 pH Field Analysis Set for the direct determination of the pH of soils (and liquids) a special electrode is used.
  • Measurement of pH is based on semi conductor technology.
  • The special, sturdy electrode, contains an Ion Sensitive Field Effect Transistor (ISFET) sensor, a silver/silverchloride potassium-chloride reference system and a thermistor to allow for automatic temperature compensation.
  • The electrode has a measuring range of 0-14 pH with an accuracy of 0.03 pH.
  • Measurement depth is 80 mm.
  • The electrode is used in combination with a multimeter.
  • The complete set includes the multimeter with electrode, a small pre-drill auger land with thumb spatula and calibration liquids

EC-Probe For Salinity Measurements
Eijkelkamp 14.01 EC-Probe For Salinity Measurements

Product Features
  • To determine the salinity of a soil electrically.
  • In combination with an earth resistivity meter, the resistivity of the soil is measured, and this reading is subsequently converted into electrical conductivity. This conductivity depends on the structure and texture of the soil, the moisture content and the salinity of the ground water.
  • The method is less accurate than a soil sample analysis in a laboratory set-up, but for an estimate of the salinity this method is highly satisfactory.
  • Eijkelkamp 14.01 EC-Probe For Salinity Measurements can be used to perform many comparative measurements in a certain area in a short period of time.
  • Consist of a stainless steel bar, provided with a detachable handle. The bar is provided with a 10 cm graduation. Inside the actual probe, at the bottom of the bar, there are four electrodes, separated by a sealing ring and a insulation ring.
  • Proper contact (= low contact resistance) with the surrounding soil is necessary to facilitate measurements with the EC-probe.
  • To establish proper contact, first the gouge auger is used to make a pilot hole to the desired depth. The drilled out soil can be used as a reference sample to determine the calibration curve.
  • In every EC-measurement, the temperature of the soil stratum that is to be read must also be measured. For this purpose, the tip of the probe is provided with a temperature sensor.
  • Having measured the earth resistivity, the temperature correction factor is determined. The temperature coefficient can be read before the electrical conductivity is calculated.
  • The standard set inlcudes: the EC-probe, an earthresistivity meter, the single gouge auger, a spatula and a strong transport bag.
