Product Description
Altek Handheld Universal Thermocouple Calibrator- Model 422
Model#: 422
Capabilities and Features:
- 14 Thermocouple Types: Supports types J, K, T, E, R, S, B, N, G, C, D, P, L, U, and millivolts (mV).
- Dual Functionality: It can both source (simulate) a thermocouple signal for testing instruments and read (measure) actual thermocouple sensors.
- Quik-Chek™ Switch: Allows users to instantly recall three preset output temperatures (HI, SET, and LO) for each thermocouple type, making repetitive calibrations much faster.
- High Accuracy: Features a typical accuracy of \(0.4^{\circ }\text{C}\) (\(0.7^{\circ }\text{F}\)) with a resolution of \(0.1^{\circ }\) or \(1\mu\text{V}\).
- Isothermal Block: Includes an exclusive isothermal block that ensures high stability and accurate cold-junction compensation. [1, 2, 3, 5]
Technical Specifications:
- Accuracy: (0.008% of Reading + 0.006mV
- Power: Operates on a standard 9V alkaline battery with approximately 40 hours of nominal life.
- Protection: Built-in protection against accidental connection to 120V AC/DC.
- Output Adjustment: Uses a single speed-sensitive rotary knob for both rapid coarse and fine adjustments
