Page 4: General Description
General Description The Sensit® Infrared Ethane Dectector, referred to as “IRed”, is designed to detect the presence of ethane in a methane sample. The IRed can detect 250 parts per billion (ppb) up to 1000ppm ethane. The IRed is used to determine if methane detected in the range of 50-2000ppm is of similar make-up to that of pipeline gas (which contains ethane) or is naturally occurring methane from other sources such as organic decay. The IRed is not designed for high concentrations or determining actual ethane content from within a pipeline. The IRED senses gas using Infrared (IR) Absorption Spectroscopy in combination with an electronic narrow band pass filter. This technology utilizes an infrared light source with an output that is changed when certain gases absorb the light output. The filter only allows specific light wavelengths to be monitored and measured. The concentration of gas is proportional to the amount of specific IR light absorbed and is displayed in PPB or PPM. The IREDhas a large display indicating concentration and other instrument functions such as battery charge and performance. An internal pump provides rapid sampling into the detection chamber. Audible and visual alarms indicate when preset alarms are exceeded. Bluetooth data transmission provides communication of real time and stored data. Optional GPS and Data Logging allow for further recording of time, date and location data. GRAPHIC DISPLAY FILTER INFRARED COMMUNICATIONS “D”... -

Page 9: Housing Features
Housing Features Battery Pack The battery pack is located on the back side of the instrument housing. The batteries are Lithium Ion rechargeable. The batteries are only available from Sensit Technologies. To remove the battery pack turn the retaining screws ¼ turn. Pull the bottom of the pack away from the main housing. Recharging of the battery pack requires removal from the main housing. To replace slide the top tabs of the battery pack into the retainers at the top of the main housing. Push the bottom into place and turn and lock the retaining screws. The battery pack has LED’s to indicate charge status. Charging should only be performed in an area know to be free of combustible gases. Charge Charging Status Charger Complete Connection (Green) (Red) (Yellow) The battery pack may also be charged while operating in a vehicle. Connect the 12vdc adapter into the vehicle power outlet and the external port on the battery housing. This can be connected and disconnected while the IRED is operating. When the charger is disconnected, the words “WARM UP”, “PLEASE WAIT” (flashing) are displayed and a 180 second countdown is started/displayed. During the 180 second countdown, the user can not perform a measurment until the countdown expires. The instrument will only operate when on battery power. -
Page 10: Filters
Gas Inlet and Outlet Located on the front of the main housing is the gas inlet and outlet. Both are fitted with luer- style connections for easy connection to probe accessories. The center connection is the gas inlet. To the right is the outlet. Do not block gas outlet. Shoulder Strap attachment “D” rings are located on each side of the main housing for shoulder strap attachment. Clips on the strap will attach securely. Hydrophobic Filter Assembly WARNING: Do not operate without proper filter. Damage may occur to the pump and other internal parts. Only change filter with pump or instrument off. The gas inlet is protected by a hydrophobic filter. It is accessed by: 1. Detach any probe assembly 2. Twist and remove filter cap 3. Remove and replace filter disc 4. Check “O” ring inside cap 5. Replace filter cap 6. Performed flow block test Additional filters are located in each of the accessory probe assemblies. -
Page 11: Field Operations
Operation and Field Use 1. To activate the instrument push the POWER (A) button until the display illuminates. The following warm up sequence will occur on the display (a-g): a. Sensit Logo will appear b. System Check i. Failures will be listed 1. Pressing the A button will turn off the instrument 2. Pressing the B button will display the next error if more than one has occurred 3. Pressing the C button will skip past the error to continue warm up. A password is required to skip the error message. Wrong password will cause the error message screen to be displayed. ii. Use the B and/or C button to ajdust the password. iii. Press the A button to accept the entry. c. Serial number, Software Revision, Date and Time. d. Warm up is indicated “PLEASE WAIT” with a 600 second countdown timer. The countdown timer will begin after an initial warm up of 5-10 minutes. e.

Pressing the A button will turn off the instrument. - Page 12 Operation and Field Use (Continued) 2. From the IRED”, “READY FOR MEASUREMENT” display press and release the B button to “START” a measurement. a. The instrument will perform a zeroing process i. Apply air known to be free of methane gas ii. Press the B button “OK” to accept iii. “SAMPLING CLEAN AIR” will be displayed with information showing the outputs for methane (M) and light level (L) sensors. A stable reading must occur before the process automatically continues. iv. A cell containing methane is introduced to the light path internally as displayed by “ METHANE CELL-IN”. Also displayed is information showing the outputs for methane (M) and light level (L) sensors. A stable reading must occur before the process automatically continues. v. If the reading is not stable the zeroing process will automatically re-initiate indicated by a “RE-ZEROING” message. This process requires and addition 120-180 seconds as indicated by a countdown timer. vi. A stable reading is indicated by a displayed message “PLEASE BEGIN SAMPLING” b. Attach the probe and place the probe in the area to be tested. Press the B button “START” within the time indicated on the countdown timer. c. The measuring of ethane is indicated by the “MEASUREMENT” heading and the ppb/ppm readings. During a measurement, 4 consecutive 10 second readings are taken. Each reading is averaged over the 10 second period before it is displayed. The display will be updated with the reading every 10 seconds until the 40 second period has elapsed. The final reading is indicated when the “RESULT” heading is displayed. i. If the methane concentration is too high a message will be displayed indicating the need to re-zero and attempt measuring again.
