OM-CP-QUADTEMP-A-Series

Supported Applications

The Omega OM-CP-QUADTEMP-A Series comprises battery-powered, stand-alone thermocouple temperature data loggers within the NOMAD® Family. These devices are designed for recording and analyzing temperature profiles in environments requiring multi-channel monitoring. The series supports real-time operation when connected to a PC via USB interface cable (OM-CP-JFC200), allowing users to monitor and record data simultaneously.

Applications include scenarios where programmable start times, automatic cold junction compensation, and nonvolatile solid-state memory are required for capturing up to 500,000 readings per channel. Data is retrieved via USB (115,200 baud) and analyzed using Windows® software that displays results in graphical or tabular formats.

Operating Conditions & Performance

The series operates within an ambient temperature range of -20 to 60°C (-4 to 140°F) with a humidity rating of 0 to 95% RH non-condensing. Measurement capabilities vary by thermocouple type, supporting the following ranges:

• Type J: -210 to 760°C (-346 to 1400°F)
• Type K: -260 to 1370°C (-436 to 2498°F)
• Type T: -260 to 400°C (-436 to 752°F)
• Type E: -260 to 980°C (-436 to 1796°F)
• Type R: -50 to 1760°C (-58 to 3200°F)
• Type S: -50 to 1760°C (-58 to 3200°F)
• Type B: 60 to 1820°C (140 to 3308°F)
• Type N: -260 to 1300°C (-436 to 2372°F)

Accuracy specifications are ±0.5°C for J, K, T, E, and N thermocouples (at uniform 20°C internal temperature) and ±2.0°C for R, S, and B thermocouples under the same conditions. The internal ambient channel offers an accuracy of ±0.5°C (0 to 50°C) or ±0.9°F (32 to 122°F). Resolution is 0.1°C for J, K, T, E, N types and 0.5°C for R, S, B types; the internal channel resolution is 0.05°C (0.09°F).

Recording intervals are selectable from 4/sec to 1/day via software. Time accuracy is ±1 min/month when the RS232C port is not in use.

Configuration Options

The series offers configurable options for calibration, display presence, and accessories:

• Housing & Materials: Black anodized aluminum enclosure. Dimensions are 68 H x 183 W x 26 mm D (2.7 x 7.24 x 1.02") for the OM-CP-QUADTEMP-A and 68 H x 183 W x 29 mm D (2.7 x 7.24 x 1.14") for the OM-CP-QUADTEMP2000.
• Power Supply: Powered by an included 9V lithium battery or external power via a universal 120/230 Vac 50/60 Hz AC adaptor (included). Battery life is typically 18 months for the OM-CP-QUADTEMP-A. For the OM-CP-QUADTEMP2000, typical battery life is 18 months with display off and 3 months with continuous display use.
• Connectivity: Female subminiature connectors for thermocouple inputs; USB interface (cable required) at 115,200 baud. Load resistance is 1000Ω, with 100Ω recommended.
• Memory & Data Format: Nonvolatile solid-state memory stores up to 500,000 readings per channel (individual channels can be disabled to increase memory). Data format includes date and time stamps in °C, °F, °K, or °R.

Available options include the OM-CP-JFC200 Windows software package with a 1.8 m (6') USB interface cable, OM-CP-BAT103 replacement 9V lithium battery, and an optional NIST calibration certificate. The KTSS-HH probe is sold separately.

Key Product Differences

The series distinguishes between two primary model configurations:

• OM-CP-QUADTEMP-A: A 4-channel temperature data logger with one internal ambient channel. It does not include an LCD display.
• OM-CP-QUADTEMP2000: Includes all features of the OM-CP-QUADTEMP-A but adds an integrated LCD display for local viewing.

Both models are available with or without a NIST calibration certificate (indicated by the -CERT suffix). The series supports digital temperature calibration through software. Weights differ slightly: 430 g (15.2 oz) for the OM-CP-QUADTEMP-A and 420 g (14.8 oz) for the OM-CP-QUADTEMP2000.
