HLD6000 Refrigerant Leak Detector

Detectable refrigerants: with sniffer probe for single gas detection: R744 (CO2), R600a/ R290 


  • Newly developed, slim, ergonomically shaped sniffer probe
  • Intuitive touchscreen display
  • USB interface as well as an optional I/O module and an optional fieldbus module available for acquiring and using measurement data and integrating into local networks
  • Even easier to operate than its predecessor, the HLD5000
Basic Specifications

  • Detectable refrigerants: with sniffer probe for single gas detection: R744 (CO2), R600a/ R290 and with universal Smart sniffer probe: halogen-based refrigerants
  • Minimum detectable leakage rate: with sniffer probe for single gas detection: 1,0 g/a 0.03 oz/yr and with universal Smart sniffer probe: 0,5 g/a 0.014 oz/yr
  • Response time < 1 s
  • Leakage rate units: g/a, mbar l/s, oz/yr, lb/yr, Pa m3/s
  • Warm-up time < 30 s 
  • Digital inputs/ outputs: 10 inputs, 8 outputs (for use with l/O 1000 module)
  • Serial interface RS232 (for use with l/O 1000 module) or field bus systems (for use with Profibus module)
  • Weight 4,5 kg / 10 lb
  • Allowed operating temperature 5 - 50°C / 4 - 120°F
  • Gas flow 320 sccm
  • Warrently 3 years

The new sniffer probe compact, light and slim:
  • Two LED lights in the sniffer tip simplify leak detection at poorly lit inspection locations, facilitate precise leak location and notify the user by flashing when the allowable leakage rate is exceeded
  • A colour LED status light continually alerts the operator about the operational readiness, measuring operation, exceeding your allowable leakage rate, as well as error warnings

Touchscreen display:

  • New INFICON human-machine interface has an intuitive menu navigation and makes using the leak detector especially easy
  • A leakage rate trend graphs any leaks on the easy-to-read front panel making leak detection even more efficient 

Interfaces and networks:

  • Integrating the HLD6000 into local networks is simple
  • Offers variety of analog and digital interfaces via the optional I/O module
  • Optional fieldbus module also available
  • Besides transmitting measurment data from the iternal memory, the USB interface also allows the user to store the measurment data directly to a connected USB flash drive
  • USB interface is also used for easy software updates

Detection system:

  • Long-life infrared sensor offers greater sensitivity and an extremely short response time
  • Specifically developed for the detection of refrigerants, which helps eliminate false alarms due to water, solvents, or other contaminents

Dual inlet system:

  • Proven dual inlet system continually compares the background concentration and the measurement of gas flow, thus reducing false alarms to a minumum

Optimised sniffer probe:

  • The HLD6000 can be equipped with sniffer probes individually optimised to the gasses to be detected
  • In addition to sniffer probes for CO2 and R600a/ R290, a universal Smart sniffer probe for halogen-based refrigerants is available

Low operating costs for service and maintenance:

  • Wear-free sensor which maximizes user uptime
  • Redesigned COOL-Check holder allows you to replace the built-in test leak quickly, pecisely and is easily changed by hand


  • Especially slim and ergonomically designed sniffer probe with status and LED lights
  • Intuitive touchscreen with leakage rate graph
  • USB interface for storing measurement data for software updates
  • HLD6000 components (probes, base units, consumables and accessories) are compatible/ interchangeable with its predecessor HLD5000
  • Optional I/O module and optional fieldbus module facilitate into local networks
