Reference Measuring Instruments ALMEMO® Reference measuring instrument for temperature and humidity. Multi-channel measuring instrument with nine measuring inputs for Pt100 sensors and Pt100 psychrometers. High-precision measuring with resolution of 0.001 K. For calibration laboratories, quality assurance procedures, and monitoring of test and measuring rooms. For use either as PC interface or with external memory connector as data logger. Technical data and functions Multi-channel instrument for high-precision measuring Reference measuring instrument ALMEMO® 8036-9 ensures very high levels of resolution, precision, and linearity when measuring temperature, using up to nine Pt100 sensors - or alternatively up to four Pt100 psychrometers. This reference measuring instrument is suitable for use as calibration standard in calibration laboratories, for quality assurance procedures, or as a multi-channel instrument for highprecision measuring operations, e.g. in test and measuring rooms or climate chambers. With the Pt100 the measuring ranges have been expanded considerably, up to +670 °C at the highest resolution of 0.001 K and up to +850 °C at a resolution of 0.01 K. The measured value units can be programmed to either °C / K / °F. Reference measuring instrument ALMEMO® 8036‑9 operates with special ALMEMO® plugs incorporating expanded programming possibilities. These plugs, it should be noted, cannot be interchanged with the ordinary plugs used with ALMEMO® V6 / V7 measuring instruments. Very high precision thanks to multi-point adjustment and input of coefficients for the Pt100 characteristic This very high level of precision is achieved by calibrating the measuring chain comprising Pt100 sensor and measuring instrument. For each individual sensor there are two error correction methods available. 1. Multi-point adjustment in up to 35 temperature points 2. Input of coefficients R0 and A, B, C for the Pt100 characteristic as per the Callendar / Van Dusen equation Linearization is then performed using the sensor-specific Pt100 characteristic. Both correction procedures can be used for any sensor simultaneously. The correction values from multi-point adjustment and the coefficients of the Pt100 characteristic are saved in the sensor connector. Sensors are identified by means of a programmable 10-character alphanumeric designation stored in the sensor connector and a serial number. Similarly, for the purpose of monitoring the calibration interval, the date of the next calibration due and the calibration interval can be programmed and saved in the sensor connector. High-precision humidity measuring with atmospheric pressure compensation and calculation as per Dr. Sonntag and W. Bögel The Pt100 psychrometer incorporates two temperature sensors assigned to two measuring inputs. 72 The digital atmospheric pressure sensor integrated in the ALMEMO® device ensures that any pressure-dependent humidity variables are pressure-compensated automatically. Humidity is calculated on the basis of formulae as per Dr. Sonntag and the enhancement factor as per W. Bögel (correction factor fw(t,p) for real mixed gas systems). This substantially widens the measuring range and improves the accuracy of humidity variable calculations. Temperature is measured to a resolution of 0.001 K, relative humidity to 0.01 % RH, and dewpoint temperature to 0.01 K. Humidity variables are calculated from the three primary measuring channels (real measurable variables) - dry temperature (TD °C), wet temperature (TW °C), and atmospheric pressure (mbar). In the second ALMEMO® plug (dry sensor) there are up to three humidity variables, simultaneously programmable: relative humidity (%), dewpoint (°C), and mixture (g/kg), abs. humidity (g/m³), vapor pressure (mbar), enthalpy (kJ/kg). Other equipment - Five LEDs for indicating various operating states - One pushbutton for switching the device on / off and to start / stop a measuring operation - Data logger mode with plug-in ALMEMO® memory connector with micro SD card (accessory) - Two ALMEMO® output sockets for simultaneously connecting a PC or network and an ALMEMO® memory connector ALMEMO® Connect configuration software The ALMEMO® Connect software can be used on a PC to program all sensor parameters in the Pt100 sensor or in the Pt100 psychrometer: measuring range / resolution, units, smoothing, text description, calibration date and calibration interval, multipoint adjustment, locking level. The ALMEMO® Connect software can also be used to completely program the device. WinControl software for measured data acquisition The WinControl software (accessory) can be used to acquire and document measured values from the reference measuring instrument. In the calibration laboratory the reference measuring instrument (reference standard) and the ALMEMO® device (test item) can be networked together and evaluated using WinControl. 11/2025 • We reserve the right to make technical changes.
