An accessory head, not a stand alone meter
Fieldpiece Dual-Temperature Accessory, Model ATH4
The Fieldpiece Dual-Temperature Accessory, model ATH4, measures two temperatures simultaneously using the included k-type, wrap tab beaded thermocouples. The technology inside the ATH4 provides superior temperature compensation in rapidly changing environments commonly found while performing field service. Use the ATH4 to find Delta T and just about any temperature split you want to measure. Displays T1, T2 and T1-T2 on your Fieldpiece meter, handle or data logger. It is included with the HVAC Guide® System Analyzer to get target superheat and for the Target Evaporator Exit Temperature test. Fieldpiece offers a wide variety of k-type thermocouples for various HVAC specific applications. Use pipe clamp T/Cs with the ATH4 to check for blocked filters. Use wet and dry bulb thermocouples to find target superheat.
Características técnicas
- Outputs: Switchable: T1, T2, T1-T2, standard male banana plugs
- Calibration: Two externally adjustable pots
- Conversion rate: 1mVDC per 1º
- Range: -50 to 1800ºF (-46 to 982°C)
- Resolution: 0.1º for meters with 0.1mVDC
- Battery: Standard 9V
- Battery life: 200 hours continuous
- Auto-off: After 15 minutes
- LED indication: green for "On", red for low battery
- Max input voltage: 60 VDC, 24 VAC
- Strong RF fields can adversely affect the converter performance.
- Operating temp: -30 to 120ºF (-34 to 49°C)
- Storage temp: -4 to 140ºF (-20 to 60°C)
- Probe insulation: Teflon, to 500ºF (260°C)
- System accuracy* at 75ºF ± 5ºF (24°C ±3°C) ambient, after ice bucket calibration:
- ±1ºF, -50 to 165ºF (±0.5°C, -46 to 73°C)
- ±2ºF, 165 to 350ºF (±1°C, 74 to 176°C)
- ±3ºF, 350 to 1700ºF (±2°C, 176 to 926°C)
- Converter accuracy: ±0.5%+3.6ºF (2°C), -50 to 1800ºF (-46 to 982°C)
- Thermocouple accuracy: ±4ºF (±2°C) or ±0.75%, whichever is greater, -30 to 1500ºF (-34 to
- 815°C)
* To calculate system accuracy from components, add up the accuracy specifications for the meter, the thermocouples, and the converter. For example, at 100ºF(38°C), add the accuracies for a DMM(±1ºF/ ±0.5°C), a thermocouple (±4ºF/ ±2°C), and the converter (±4ºF/±2°C). The system accuracy for these individually calibrated components is ±9ºF(±4.5°C). If the actual temperature was 100ºF(38°C), the meter could read as high as 109 (42.5) and as low as 91 (33.5). By contrast, after a simple "ice bucket" system calibration, the meter would read between 101.0 (38.5) and 99.0 (37.5).
