Gazeeka Model 870 Moisture Gauge


Our flagship Model 870 moisture sensing platform for large square balers, available with numerous options for mounting and tractor cabin integration.

• Isolate potential hot spots as you bale
• Bale without stopping to check moisture levels
• Displays: Instantaneous, Maximum (Peak) and Average moisture.

The most accurate moisture gauge on the market.

If using an 870s with an early model steamer, please also add the 870 steamer extension cable to your order. 870i (ISObus) models do not need this option.

High Performance

Moisture content measured accurately and reliably. Based on total moisture (as oven dried), in cured hay.

Proven Technology

Successfully operated in the cotton industry and in coal and minerals for 25+ years, where the precision is typically 0.3% to 0.5%.
For hay, precision can be expected to be ± 0.5% on cured hay.


Very low energy – high frequency electromagnetic waves are transmitted between two antennae positioned in a non-contact configuration for ease of operation. The measuring “area” is approximately a square foot right through the bale at power levels less than the standards set for mobile phones.


The two antennae are mounted on the baler so as to analyse the hay bale as it exits the baler. The LCD, touch screen moisture display unit, is mounted in the tractor cabin, providing updates every few seconds. The unit also has an audible alarm for high moisture levels.


Calibrated for cured hay. Large square balers only.
