Tru-Test MilkHub Application Instructions

Tru-Test MilkHub™ Heat Detectors
Application Instructions

Warm the MilkHub Heat Detectors

For best adhesion the MilkHub Heat Detectors should be applied
at about 350 C
• In cold weather they can be warmed to this temperature by
keeping them inside your overalls
• A chilly bin with a warm hot water bottle wrapped in a
towel, or a wheat bag, can also be used to warm them
• Do not overheat as this overactivates the adhesive and
makes application more difficult

Select the correct position

Placing the MilkHub Heat Detector in the correct position is
important for best results
• Position over the centre of backbone
• Position just to the rear of the hips by approximately one
hand width
• Ensure the position is not sloping forwards. If it is, the Heat
Detector may not get rubbed sufficiently. Adjust the position
forward or backward slightly to ensure it is flat or
sloping backward

Prepare the position correctly

The MilkHub Heat Detector is designed to stick to clean, dry,
firmly attached cow hair
• Remove any loose hair by hand
• Wipe off any dirt, dust or excess moisture with a towel
• If the area is excessively dirty brush with a curry comb
• No need to clip or shave the area

Spray on tack coat

Spraying the prepared position with a tack coat is recommended for optimum adhesion, particularly in damp conditions
• Use 3M77 spray (available from Tru-Test 0800 6455 482)
• Apply a thin layer of spray
• Wait to tack for a minimum of 1 and maximum of 10 minutes
• Rotary - spray at entry and apply the MilkHub Heat Detectors at exit
• Herringbone - work by spraying along the row first and then returning again to apply the MilkHub Heat Detectors
