A&D Co Temperature Calibrator MX-43 Digital Thermometer Kit
The A&D Co Temperature Calibrator MX-43 (often listed as AX-MX-43) is a specialized, precision digital thermometer kit designed for calibrating the drying temperature of A&D's high-performance moisture analyzers. It ensures that the halogen lamp heater produces accurate temperatures, which is critical for consistent moisture content results in laboratory and industrial settings.
Core Features and Components
  • Compatibility: Designed exclusively for use with the A&D MS-70 and MX-50 moisture analyzers (not for MF-50 or ML-50).
  • Included Components: The kit typically consists of a digital thermometer display unit and a specialized sensor pan (with a built-in K-type thermocouple).
  • Digital Thermometer: Features a \(3 \frac{1}{2}\) digit LCD display with a, "Data Hold" (D-H) function, and a low-battery indicator.
  • Calibration Range: Designed to calibrate drying temperatures, typically at \(100^{\circ}C\) and \(160^{\circ}C\).
  • Robust Sensor: The sensor pan is designed to fit directly into the analyzer heating chamber for direct heat measurement. 
Key Benefits
  • Accuracy & Reliability: Ensures the drying temperature on the pan matches the unit's setting, enabling compliance with GLP, GMP, and ISO standards.
  • Quick Calibration: The process takes approximately 15 minutes per adjustment point, improving laboratory efficiency.
  • Traceability: It is often sold with a traceability certificate and certificate of measurement.
Typical Specifications (Thermometer Unit)
  • Display: \(3 \frac{1}{2}\) digit LCD.
  • Battery: 9V battery (typ. 200 hours life).
  • Operating Temperature: \(0^{\circ}C\) to \(50^{\circ}C\) (\(32^{\circ}F\) ~ \(122^{\circ}F\)).
  • Sensor Type: K-type thermocouple. 
Operation Notes
  • Before Use: Install the 9V battery before using.
  • Usage Limitations: When calibrating, avoid using the Hold function; ensure the sensor is connected properly.
  • Safety: Do not input a voltage that exceeds 24VAC or 60VDC to the unit.
  • Storage: Keep the sensor clean and dry, storing it safely between uses.
