Supported Applications
The Omega OM-EL-GFX Series comprises portable data loggers designed for temperature, relative humidity, dew point, and thermocouple measurements. These units feature a high-contrast graphic LCD display with real-time graphing capabilities, allowing users to monitor conditions directly on the device or download historical data via Micro USB connectivity using included Windows software.
Documented measurement functions include:
- Temperature only: Internal sensor monitoring for general environmental tracking.
- Temperature & Humidity: Simultaneous recording of temperature and relative humidity, with calculated dew point values available on specific models (40 to 100% RH @ 25°C).
- Thermocouple Inputs: Support for Type K, J, and T thermocouples in single or dual-channel configurations.
- External Thermistor Probes: Dual channel support for external thermistor probes (OM-EL-GFX-DTP), including options with sealed glycol-filled chambers for temperature stabilization.
Operating Conditions & Performance
The series operates within an ambient range of -10 to 40°C (-14 to 104°F). Measurement ranges and accuracy vary by model configuration:
- OM-EL-GFX-1 (Temperature): Range -30 to +80°C (-22 to 176°F); Accuracy ±0.1°C (±0.2°F) typical, ±0.5°C (±1.0°F) maximum.
- OM-EL-GFX-2 & OM-EL-GFX-2-PLUS (Temp/Humidity): Temperature range -30 to +80°C (-22 to 176°F); Humidity 0 to 100% RH. Accuracy for temperature is ±0.5°C (±1.0°F) typical / ±2.0°C (±4.0°F) maximum on OM-EL-GFX-2, and improved accuracy of ±0.2°C (±0.4°F) typical / ±0.8°C (±1.6°F) maximum on OM-EL-GFX-2-PLUS.
- OM-EL-GFX-DTC & OM-EL-GFX-TC (Thermocouple): Supports Type K (-200 to +1350°C / -328 to +2462°F), Type J (-200 to +1190°C / -328 to +2174°F), and Type T (-200 to +390°C / -328 to +734°F). Accuracy is ±0.5°C (±0.9°F) typical.
- OM-EL-GFX-DTP (Thermistor): Range -40 to 125°C (-40 to 257°F); Resolution 0.1°C (0.2°F).
All models provide a memory capacity of 256,000 readings and are powered by two replaceable ½ AA 3.6V lithium batteries (Part No: OM-EL-BATT), offering approximately one year of battery life.
Configuration Options
The series offers configurable options for housing protection, sensor inputs, and accessories to address specific logging requirements:
- Housing & Protection: Models OM-EL-GFX-1, OM-EL-GFX-2, and OM-EL-GFX-2-PLUS feature IP67 rugged construction when the USB cover is attached. Other models (DTC, TC, DTP) do not carry this rating.
- Display & Interface: All units include a 128x128 backlit graphic screen for tabular or graphical data display and three input buttons for operation. A Micro USB interface enables PC-based setup and data download; the unit can also be powered continuously via a wall adapter.
- Start/Stop Logic: Logging can initiate immediately, at a delayed time (e.g., 10:30:00), or upon reaching a specific temperature/RH threshold. Users can mute alarms and reset summary data on-device.
- Accessories & Probes:
- Included mounting clip with integrated magnet for wall or metal surface attachment.
- Spare thermistor probes (OM-EL-PROBE-TP-2-1M) and higher accuracy options (OM-EL-PROBE-TP-A-3M, OM-EL-PROBE-TP-A-GLY-3M) for the DTP model.
- Extension cables available in 1.5 m (5'), 5 m (16.5'), and 10 m (33') lengths for thermistor probes.
Key Product Differences
The OM-EL-GFX Series is differentiated by sensor type, channel count, and physical dimensions:
- OM-EL-GFX-1: Single-channel internal temperature logger. Dimensions: 88 H x 48.5 W x 30.5 mm D (3.46 x 1.91 x 1.20"). Weight: 99 g (3.5 oz).
- OM-EL-GFX-2 & OM-EL-GFX-2-PLUS: Internal temperature and humidity loggers with varying accuracy levels. Dimensions match the GFX-1.
- OM-EL-GFX-DTC: Dual-channel thermocouple logger (K, J, T types). Includes two free 1 m Type K insulated beaded wire thermocouples. Dimensions: 102 H x 48.5 W x 30.5 mm D (4.06 x 1.91 x 1.20"). Weight: 105 g (3.7 oz).
- OM-EL-GFX-TC: Single-channel thermocouple logger. Includes one free Type K insulated beaded wire thermocouple.
- OM-EL-GFX-DTP: Dual-channel external thermistor probe logger. Dimensions: 101 H x 48.5 W x 30.5 mm D (3.98 x 1.91 x 1.20"). Includes two standard thermistor probes with stainless steel tips.

Great value logger
Real nice logger. It doesn't say on the site but my unit (OM-EL-GFX-DTC) came with 2 type k thermocouples that have 5 foot leads and 4 inch long 1/8" diameter probe. To set up the first time you need to get the software which is found by the quick link on the bottom of their web page. Go to the data loggers and scroll to OM-EL-WIN-USB. It says it will log for over 2 years with the included batteries, time will tell on that one.

What type connectors are the sensor inputs???
The connectors are sub-mini SMPW female that require SMPW-(TC TYPE)-M, ex. SMPW-K-M.

Are there specs available for response times of TC/thermistor options?
Thank you for your question. We will require more information to help on this question, please email the DAS team at DAS@OMEGA.COM”

is the datalogger available with NIST Calibration certificate
Hello, thank you for your question. Yes, you would need to use part number OM-EL-GFX-2-NIST when placing the order, that is the same logger including a NIST Cert.

OM-EL-GFX-DTC has 2 inputs and 130K measurement storage. When logging both inputs, does that mean there are 65k per input or does the combined measurements make a single data point?
Hello, thank you for your question. The memory for this unit can store up to 252,928 readings, that means 126,464 readings per channel.

Does this data logger come with a OMYL-CI cable, or does that need to be purchased separately?
Hello Cj,
Thank you for your interest in Omega .The OMYL-CI cable is not included and must be purchased separately in order to read current.
