Hygrometer and environmental monitoring software

HART Scientific, represented by Fluke Australia , has bundled its digital thermal hygrometer with its LogWare III environmental monitoring software, enabling real time recording and viewing of all data.

The Model 1621 Value Kit includes the temperature and humidity logger, two sensors, a sensor case, a 7.62m sensor extension cable and LogWare III. Each sensor is calibrated for temperature and humidity and contains its own calibration data so that sensors can be removed from the logger and sent in for recalibration. This allows the logger to be used continuously, ensuring consistent, high-quality measurements without interruption or the need to purchase a back-up unit.

The Hart Scientific Model 1621-S reads temperature to ±0.25°C over its range of 15°C to 35°C and it records humidity to ±2% RH from 20% to 70% RH. The 1621-H reads temperature to ±0.125°C over its calibrated range of 16°C to 24°C and measures humidity to ±1.5% RH from 20% to 70% RH. NIST-traceable certificates are provided with each sensor showing data for temperature and humidity. The total range for both models is 0°C to 50°C and 0% to 100% RH. LogWare III is a Windows application that retrieves, stores and analyses data from the logger. The software can import data batches from PC cards or directly from the logger's onboard memory. LogWare III can read data in real time via an RS-232 cable.

Real time data may be logged from one or both sensors, providing up to two temperature and two humidity inputs. All data is stored in a single database that is retrievable based on date and time ranges and sensor identifiers, which can be modified to indicate locations. Configurable user accounts and access levels ensure appropriate security and integrity of all stored data.

The real time data may be viewed in customisable graphic and statistical formats. Graphs may be displayed for temperature and humidity for one or both sensor inputs in user-selectable time increments. A variety of statistical functions can also be shown for each input including min, max, average and standard deviation. Alarm settings accompany downloaded or real-time data and may be highlighted in the graphs and in the displayed statistics.

For previously stored data, LogWare III allows on-screen viewing of raw data. It also exports data to file formats that may be viewed in Excel or other common spreadsheet and database programs.
