The PCL41 Series pressure standard incorporates features found in high-end standards into an affordable, portable benchtop unit. The microprocessor-based controller allows the user to adjust display filtering for the particular application. The front panel tare allows zeroing of the display with a single pushbutton. Testing pressure switches is done by utilizing the display hold capabilities of the microprocessor. An external connection is completed when the pressure switch under test changes state. The switch freezes the display, which shows the true actuating pressure. The microprocessor allows adjusting of the unit for increased or decreased resolution. All options associated with the DP41 panel meter are available on this benchtop unit. Combining the PCL41 with its unique options can turn the unit into a sophisticated data collection system. Scalable analog outputs, RS-232 or RS-485 communications and mechanical relays are all available options with the PCL41.

CL120 Series Calibration COOL/HEAT Source
The CL120 Series is capable of simultaneous heat and cool sourcing in one unit and is available with either one or two modules. You select the combination of modules: COOL Source only, HEAT Source only, COOL Source and HEAT Source, or two HEAT Sources. Both the COOL and HEAT Sources are available with the Universal Jaw or a "five hole block."
A dual module system with simultaneous cooling and heating is a significant advantage, because temperature sensors are rarely tested at only one temperature. The most common procedure is to test at 0°C (32°F) and at the maximum temperature, thereby characterizing the offset and gain errors. Two HEAT Source systems may also be ordered.

The CL134 Series has the same features as the CL120 but includes measurement capabilities. This additional feature simplifies the testing of temperature sensors by conveniently housing both the Source and Measure in one package. The CL134 Series has three distinct capabilities:
1. A COOL Source (either Universal Jaw or "five hole block") with range down to -30°C (-22°F)
2. A HEAT Source with range to 500°C (932°F) with Universal Jaw or range to 700°C (1292°F) with a "five hole block." The CL134 Series may be ordered with two HEAT Sources and no COOL Source.
3. Measures thermocouples, RTD's, Current and Voltage.

The TRC ice point^TM Reference Chamber relies on the equilibrium of ice and distilled, deionized water at atmospheric pressure to maintain six reference wells at precisely 0°C. The wells extend into a sealed cylindrical chamber containing the distilled, deionized water. The outer walls of the chambers are cooled by thermo-electric cooling elements. The increase in volume produced by the creation of ice crystals within the cell is sensed by the expansion of a bellows, which operates a microswitch and controls the cooling elements. The alternate freezing and thawing of the ice accurately maintains a 0°C environment around the reference wells.
The automatic operational features of this instrument eliminate the need for frequent attention, required of common ice baths. On-off cycling of a pilot light indicates proper operation of the unit at ice point temperature.
Any combination of thermocouples may be used with this instrument by simply inserting the reference probes in the reference wells. Calibration of other types of temperature sensors at 0°C may also be performed.
When accurate temperature measurements are required, the TRCIII ice point Chamber delivers the precision you need. The reference wells are maintained at 0°C to within ±0.1°C and a stability of ±0.04°C for constant ambient. Continuous cycling operation maintains constant equilibrium conditions within the cell, eliminating the slow drift often experienced in common ice baths as melting occurs.

The Omega RHCL-2 is a microprocessor based, programmable humidity calibration system that is at home in the metrology lab or out in the field performing on site NIST traceable humidity calibrations. The RHCL-2 is entirely self-sufficient and does not need compressed air or a water connection to operate, which allows this system to be truly portable. The system offers the highest accuracy available for both relative humidity and ambient temperature.
Temperature and relative humidity are controlled independently; therefore, you are not limited to performing calibrations at the surrounding ambient temperature.
The RHCL-2 uses an Optical Chilled Mirror (OCM) primary measurement technique for traceability and feedback control. Contributing to ease of use are features such as maintenance reducing Automatic Balance Cycle (ABC), an integral ambient temperature probe, and D2 chilled mirror sensor which are located in the sample chamber providing not only superior accuracy but the fastest response.
The RHCL-2 employs a unique control scheme for maintaining precise RH control. The system incorporates volumetric proportional control valves. By independently modulating the "Dry" and "Wet" valves from full-open to full-close, and all points between, any desired humidity can be quickly generated. Additionally, because the RHCL-2 is continuously monitoring the sample chamber conditions via its integral chilled mirror, it is able to instantaneously react to changes in humidity and maintain control stability.
