The CTXL Series circular chart recorders from OMEGA combine form and function in an easy to use two-channel circular chart recorder with a large, 200 mm (8") diameter chart, and dual channel LCD readout. The CTXL recorder is offered in 5 models, Ambient Temperature and Relative Humidity, Wireless Temperature/ Relative Humidity with an RF range of 90m (300 ft) line of sight maximum, dual thermocouple (J,K,T), dual process (1 V, 5 V, 10 V, or 0/4 to 20 mA), or pH/ RTD temperature.
The CTXL has a custom LCD readout that displays the current values of both channels, and can indicate the min, max or average input values as well. The display also indicates the chart speed (1, 7 or 32 day), battery status, high and low alarm indication, keypad lockout status, and battery life.
Additional features of the CTXL include dual relays with contact closures for high alarms, and dual voltage outputs for low alarms to drive external relays. A built-in audible buzzer also informs the user of an alarm condition. A hidden key (White Box) can lockout unauthorized access to the front keypad, preventing changes to the recorder settings.
The CTXL features a rugged, ABS enclosure, suitable for industrial environments, but it’s also intended to fit right in to other environments, such as museums, art galleries, computer rooms, labs, clean rooms, even hospitals. The CTXL is designed for both benchtop and wall mount operation a convenient base rotates out of the way, and is hidden by a decorative foot cover for wall mount use.
Each unit comes complete with 120 assorted double-sided charts, 2 pen sets, extra chart light, universal ac adaptor (110 to 240 Vac, 50/60 Hz), 4 D cell alkaline batteries, RS232 cable and adaptor, wall mounting kit, and quick start manual. CTXL-TRH models are also supplied with sensor probe and clip, and 1.8 m (6') probe extension cable.

We have a CTXL-TRH-W model but we have problems selecting the correct paper chart. We have the paper charts CT485-CWC and the CT485-CDF. The main problem is that both charts start the humidity scale in different points. Which one is correct?
Hi Kevin,
Thank you for the inquiry. CWC chart is weekly rotation degrees C. CDF chart is daily rotation degrees F. When you select matching temperature units in the set up menu the RH values will also match the chart range values. Refer to quick start manual to select the matching temperature units of your chart paper.
Best regards

We are trying to record Humidity and Temperatures in a Primer Booth. The operations will produce combustible vapors under normal operating conditions. Do the Model CTXL-TRH-W meet electrical requirements for class 1 division 1. If not? Recommendations?
Hi Fernando,
Thank you for the inquiry. The CTXL does not meet Class 1 requirement. We currently do not offer a similar rated product.

Your manual states that temperature calibration is not necessary. How do I justify this in an audit? Also the humidity calibration is two point. Our requirement is a 3 point calibration is this possible?
Hi Mr Cook,
Thank you for the inquiry. For temperature / RH certifications you can still verify accuracy at multiple points. If temperature reading is out of tolerance there is no adjustment. The RH adjustment is based on 2 points.
Best regards
