Cooper Atkins

Cooper Atkins 4005MK Temperature Probe Type K Mini Plug 10 ft -20 to 300 F

SKU CH-3SG4-4GFXQ

Type K thermocouple probe with mini plug and 10 ft cable measures -20 to 300 °F on pipes and surfaces

  • Product typeEnvironmental & Mechanical
  • Type K thermocouple covers -20 °F to 300 °F
  • Grounded junction gives fast surface response
  • 10 ft cable reaches distant test points
  • Mini plug fits standard Type K instruments
  • Pipe clamp design suits air and surface checks

Probe purpose and target users

The Cooper Atkins 4005MK is a Type K thermocouple probe built for HVAC technicians and maintenance engineers who need fast surface or air temperature checks. Its grounded junction and pipe-clamp design suit routine service calls on refrigeration lines and ductwork. It is not for users who require immersion readings in liquids or high-temperature processes above 300 °F.

Deciding specification

The probe covers -20 °F to 300 °F (-29 °C to 149 °C) with a 10 ft cable ending in a miniature Type K plug. This range and connector type decide compatibility with your meter; instruments that accept only Type J or standard-size plugs will not work. Buyers needing a wider span or a different connector must choose another model.

Installation notes and common issues

Clamp the sensor jaws securely around a clean pipe so the grounded tip makes full metal contact; loose fitting adds lag and low readings. Route the 10 ft lead away from hot surfaces to prevent insulation damage. A frequent mistake is plugging the mini connector into a standard socket, which gives no reading at all.

Questions about this item

How does the -20 to 300 F range translate when the probe is clamped on a pipe?

The grounded Type K junction reads the pipe surface directly, so the thermocouple reports the metal temperature across the full -20 to 300 F span without an air gap delaying the response.

What does the mini plug limit in a Type K circuit?

The miniature connector carries the thermocouple wires to the instrument and is rated for the same -20 to 300 F operating window, so it does not restrict the measurement range.

What clearance is needed to fit the clamp and 10 ft cable?

The clamp wraps around the pipe and the 10 ft lead runs to the meter, so allow enough space for the jaws to close and the cable to route without sharp bends.
