Handheld Odor Meter is packaged carefully and includes all the components necessary for full operation. Upon receipt, check the contents and find you received the items as below in good condition. The instrument kit contains: Name Q’ty OMX-TDM Base Unit Suction Nozzle AC Adaptor ‘AA’ Alkaline Battery USB Connection Cable Air Purifying Unit...
1-2. Warning Warning Do not use any adaptors except supplied original AC adaptor. Do not use in explosive atmosphere. Do not use the device where combustible and/or explosive gasses exist. The device is not designed for explosion proof. Do not dismantle the base unit.
1-3. Cautions Cautions Do not install, use, or store the unit at a place where: Ambient temperature is not in the range of -10 to 40 degree in C. (14 to 104 degree in Ambient humidity exceeds 90%R.H. Condensation occurs due to rapid temperature change. Corrosive and/or explosive gases exist.
2. General Description Handheld Odor Meter is the most popular simplified tool for odor analysis enables to show TVOC in the value corresponding to toluene gas numerically by comparing odor gases and purified air. The reading shown on the display is calculated based on our original principle. With the installation of data filing software, measured data can be transferred to PC in easy steps.
2-1. Features 2-1-1. LCD Display Name Function Blinks for about 10min for initializing when the unit is turned on. Ready ① Start measuring when it stops blinking. Displays TVOC gas concentration corresponding to toluene gas TVOC gas concentration ② from 0 to 9999 in µg/m³. corresponding to toluene gas Upper: Year-Month-Date Calendar Function...
2-1-2. Base Unit Name Function Hold 3 seconds for “peak-hold function”. (See 3-3.) ① Hold and turn on the device at the same time to set calendar. Select sampling rate. (See 3-2.) ② Set calendar. Use for “zero-point function". (See 3-4.) ...
2-2. Accessories Name Function AC Adaptor Connect to the unit during the measurement if necessary. Air Purifying Unit Attach to the unit for “zero-point function”. (See 3-4.) Exchange activated carbon when deodorization using air Activated Carbon purifying unit is not effective. Replace filter when deodorization using air purifying unit is not Replacement Filter for Air effective.
3. Measurement 3-1. Real-time Sampling Mode 3-1-1. Measurement Preparation 1. Place filter to suction nozzle. 2. Attach suction nozzle to the unit before measurement. 3. Use “AA” alkaline batteries or AC adaptor. 4. Turn on the unit at clean ambient. It takes about 10 min for the unit initializing and start measuring.
3-1-2. Measurement 1. Turn on the unit and wait for about 10 minutes until “Ready” stop blinking and the initializing is done. 2. Start measuring. 3. Use data filing software if necessary. 4. Turn off the unit when odor strength shows close to “0”. 3-2.
3-2-3. Memory Overflow Memory overflow occurs when the internal memory is full. If there is no space remained, calendar on LCD display starts blinking and data number becomes “0”. To delete saved memory, press at the same time while the unit is turned off. Keep pressing and turn on the device.
3-3. Peak-hold Function Press for over 3 seconds during Real-time sampling. By using this function, the highest value of odor strength keeps being displayed until the unit measures higher value. NOTE Press for over 3 seconds again to cancel the function. NOTE The function is not displayed on the saved data.
4. Data Filing Software Data filing software is used to transfer data from the unit to PC by using USB connection cable. 4-1. How to Download Software NOTE Register personal information in order to download the file. 4-2. How to Install Software Open “SetupTDM_en.msi”...
How to Install USD Drivers Software Install USB Drivers software before connecting USB cable to PC. 1. Download the latest software from the link as below. 2. Install the software. NOTE If PC CPU is 32bit, select “CP210xVCPInstaler_x86.exe”. If CPU is 64bit, select “CP210xVCPInstaler_x64.exe”.
4-3. Preparation Connect the unit to PC by USB connection cable. 4-4. Open Software 1. Double-click shortcut icon on desktop, or open the file from program files. 2. Confirm main screen appears. 3. Read “Handheld Odor Meter Data Filing Software Manual” for details. 1.800.561.8187 information@itm.com www.
5. Specification Detection Method Semiconductor gas sensors Object Gas TVOC, etc. Sampling Method Continuous sampling by built-in pump TVOC gas concentration corresponding to toluene gas from 0 to Detection Range 9999 in µg/m³. Digital LCD display Display 0 to 9999 in µg/m³ Toluene (500µg/m³): Reaches 90% responsiveness within 40 seconds Response Time Toluene (1500µg/m³): Reaches 90% responsiveness within 60 seconds...
6. Maintenance and Servicing 6-1. Replacement of “AA” Alkaline Batteries Replace “AA” alkaline batteries when battery status on LCD display becomes “Low”. 6-2. Replacement of Button Battery The unit uses a button battery (model: CR2032) for memory back up. When to replace: Pasts 5 years approx.
6-3. Maintenance of Air Purifying Unit Top Wire Gauze Replace activated carbon and filters in Air Purifying Unit to prevent gases absorbed in the unit. Top Filter Arrow Label Activated Carbon Bottom Filter 1. Twist the Air Purifying Unit to open. Bottom Wire Gauze Bottom 2.
6-5. Troubleshooting If you find: Check: Check battery status or connect AC adaptor. The unit does not operate. ① Check battery polarity. Close the unit to object. Connect Air Purifying Unit to Odor Strength does not change. ② clean the absorbed gas in the unit.
