Crop Quality Measurement

Crop Environment Monitoring

Ambient Air Measurement

Static or Portable Thermo-Hygrometers

Accurate and regular assessment of air humidity and temperature inside the grain store, in a grain store tunnel or being blown in from the outside ensures drying and cooling targets are reached quickly and energy efficiently.

If automatic systems are not available, our static and portable instruments are a low-cost alternative for measurement.

Key Features

  •  Digital, large displays – easily seen in low light levels
  •  Good accuracy and range – to suit most storage situations
  •  Fast response – to take quick readings in changing situations

Martin Lishman Portable Thermo-Hygrometers

Hand-held fast response meters to quickly measure air humidity and temperature in different locations.

Portable Thermo-Hygrometer 

Measures air temperature, relative humidity and dewpoint temperature.

Tunnel Hygrometer 

Measures the air stream in a grain store tunnel. Includes detachable probe and 1m connection cable.

Static Thermo-Hygrometers

Meters to measure air humidity and temperature in fixed locations.

Panel Thermo-Hygrometer 

Used in grain stores for continuous assessment of air condition.

Jumbo Thermo-Hygrometer 

Measures air temperature, relative humidity and dewpoint temperature.

Pitfall Traps

Once the store is filled with grain, Pitfall Insect Traps can be used to detect the presence of insects. They are a ‘blunder’ trap designed to take a random sample that is representative of the whole store. Pitfall Traps are used in pairs, with one at the surface and one placed approximately 8-15cm down into the grain. The traps should be placed approximately 5-6 metres apart. The traps should be checked regularly as part of a crop assurance programme. Any insects found should be carefully identified and remedial action such as cooling or fumigation carried out as required.

Floor Traps

After store cleaning, the presence of insects should be monitored by placing the Floor Traps in corners and at wall/floor junctions every 4-5 metres around the store. The traps can show where insects are and how serious the infestation is. Using Floor Traps can also demonstrate that a store is clear of insects and avoid the need for unnecessary spraying with chemicals.
