Overview
The HEATH Detecto Pak-Infrared (DP-IR™) uses highly advanced optical technology capable
of detecting methane gas utilizing the Infrared Controlled Interference Polarization Spectrometry
method. The DP-IR is the latest leak survey instrument from HEATH that greatly improves
productivity, cost and safety of walking and mobile surveys.
The DP-IR functions by using an infrared optical gas detection system. This instrument is
intended to replace the current surveying equipment using the traditional Flame Ionization
method with next-generation technology utilizing an infrared light beam, eliminating the need
for expensive gas cylinders and rell systems. It is designed to be highly selective to detecting
methane gas and will not false alarm on other hydrocarbon gases which may be encountered
during a normal natural gas leak survey.
Figure 1: The DP-IR uses advanced infrared optical technology to achieve high sensitivity
The DP-IR operates under a variety of eld conditions, including cold and hot temperatures. Its
rugged design will stand up to normal eld use and operating conditions.
The DP-IR has a built-in self-test function that will verify that the instrument is operating
properly. Using the internal calibration cell, the operator performs the self-test as part of a daily
start-up routine. While in operation, the DP-IR continuously monitors several internal parameters
to ensure that it is functioning properly. Should any of these parameters go outside of operational
limits, a constant audible alarm will sound and an ERROR icon will be displayed.

Carrying Strap
The DP-IR has a detachable hand strap secured to three mounting points on the instrument.
There is also a padded shoulder strap to accommodate different carrying preferences.
Battery Charger
The battery charger is provided to recharge the instrument after use. The charger is a universal
110 - 240 VAC, 50/60 hertz with a charging indicator. Universal adaptors are provided to convert
the style plug for different types of receptacles.

Instruction CD
The instruction CD contains the following items:
1. This instruction manual, which provides instructions on the use and operation of the
instrument.
2. Additional HEATH product information.
3. HEATH contact information.
Carrying Case
The carrying case provides protection for the instrument during storage or transportation. The
instrument should be kept in the case while not in use.
Bar Hole Probe
The bar hole probe allows for underground gas measurements to be made. A short 20” probe is
provided as standard. The probe has a built-in dust and water lter. Other bar hole probes are
sold separately.

Optional Accessories
Bluetooth Module
The Bluetooth module adds additional exibility and mobility to the DP-IR by allowing wireless
interfacing to the instrument. The industry standard Bluetooth communication protocol allows
the instrument to stream data to a PDA or PC at distances up to 30 feet (7.6 meters) for datalogging purposes.
36” Bar Hole Probe
This probe is for conducting underground methane concentration measurement at twice the depth
of the standard probe provided. The probe is designed to minimize the risk of drawing water up
into the instrument.
DC Power Adaptor
An optional DC/DC power adaptor is used to power the DP-IR from a vehicle 12 VDC system.
The adaptor isolates and minimizes electronic noise from the vehicle power system which may
interfere with or damage the DP-IR.
