5 measurements for rapid control of plant nutrition with only one device

With the COMBI 5000 in the hand, you have the most important parameters to determine the nutritional status of your plant stock professionally and quickly.

Features:
  • Universally applicable: Wide range of probes for monitoring nutritional status of your plants.
  • No application errors: The latest microprocessor technology enables automatic sensor detection: each time the probe is changed, the instrument automatically switches to the corresponding measuring mode.
  • Easy-to-use: The automatic buffer recognition during calibration also ensures a high level of operating convenience and additional safety.
  • Fast on: Simply exchange probes during the measurement without a re-start.
  • Save time: Simultaneous measurement of different parameters.
  • Always ready to go: The unit is delivered in a sturdy aluminium case, with all accessories stored safely and within reach.
  • Multilingual: Easy to understand menu is available in three languages: German, English and Russian.
  • Smart: Evaluation via the COMBI 5000 app provides quick and easy storage and interpretation of all measured values for different plants.
pH measurement

Technical data Basic unit COMBI 5000:
  • Housing: splash-proof, rugged
  • Connector: BNC plug and 8-pin-plug
  • Power: > 4000 measurements, 9-Volt-battery
  • Display: alphanumeric, reflective
  • Dimensions: 180 × 83 × 55 mm
  • Weight: 300 g

pH measurement

pH is one of the most important parameters in the plant nutrition. The absorption of nutrients by the plants is highly dependent on pH. Being specially developed for soil analysis, the electrode measures pH directly in the soil.

  • Measuring range: 0 – 14 рН
  • Resolution: 0.01 pH
  • Accuracy: 0.02 pH
  • Calibration: automatic at рН 4, pH 7. Additionally at pH 10 if required
  • Probe: gel-filled insertion probe
  • Probe length: 125 mm
  • Application: pH measurement directly in soils / substrates and in liquids
EC measurement

EC measurement

EC measurement

Electrical conductivity of an aqueous solution is directly related to the concentration of the dissolved salts. For
plant nutrition control, it is essential to measure EC of process water and nutrient solution, especially in closed and hydroponic cultivation.

  • Measuring range: 0 – 200 mS
  • Resolution: 0.001 – 0.01 mS
  • Accuracy: ± 2 % from measured value
  • Calibration: automatic
  • Probe: plastic with platinum sensors
  • Probe length: 125 mm
  • Application: conductivity measurement in liquids, e.g. nutrient and stock solutions

Activity (salinity), soil moisture and temperature measurement with multi probe

The new multi-probe is a significant further development of the previous measuring probe for direct salinity
(„activity“) measurement in the soil or substrate. In this measurement method, the measurement result depends, besides other factors, on temperature and soil or substrate moisture. These two values can now be measured with the new COMBI 5000 multi-probe.

This is made possible due to a high-frequency capacitance measurement integrated into the probe according to
the FDR technology in a measuring range of 0.5% to 80% (volumetric). The temperature measurement is carried out in the range of -10 ° C to + 50 ° C by a fast-reacting NTC sensor spattered in the probe tip.
