Humidity and temperature data loggers

Humidity and temperature data loggers Hygrometer - thermometer is designed for record of relative humidity, temperature, dew-point, optionally in combination with universal input 0-5V. Relative humidity and temperature values are stored to a non volatile electronic memory. Data transfer to the personal computer for further analysis is performed via USB, RS232, GSM or Ethernet interface by means of a proper adapter. Main applications of hygrometer: * Food and beverage industry ( HACCP) * Pharmaceutical industry * Horticulture and cultivation of plants * HVAC ( heating, ventilation, air conditioning, cooling) * Building and energy management * Research and development * Laboratories ( GLP) * Warehouses * Technological processes * Museums, archives, galleries Advantages of hygrometer: * included traceable calibration certificate from the manufacturer - Comet * fast data transfer to the PC ( full memory for approximately 30s) * variability of connection to the computer - USB, RS232, Ethernet, GSM modem * permanent connection to the PC enabled, data is possible to download even during logging * large data memory 32000 values * large dual line display with special symbols, switchable * optional display of minimum and maximum measured values ( reset of min/ max memory from PC or by magnet) * dual level alarm is enabled for each channel, alarm is indicated by blinking of the value on the LCD display or LED diode * two alarm modes are enabled: instant or with memory ( detected alarm is indicated permanently till alarm memory is cleared from the PC) * robust watertight case * easy installation, locking enabled * low power consumption from battery, battery life up to 7 years * indication of remaining battery life, easy replacement of the battery * it is possible to combine temperature and humidity measurement with two user calibrated 0-5V voltage signals * logging start/ stop is enabled in several ways: at certain time and date programmed from computer, by delivered magnet * also special logging mode is enabled, when logging runs only, if some of measured values are out of adjusted alarm limits * each data logger is possible to describe with text of maximum 32 characters * each channel is possible to describe with text of maximum 16 characters * password protection is enabled to prevent unauthorized manipulation with logger COMMON TECHNICAL PARAMETERS OF HYGROMETER Operating temperature range of data logger R3120, R3121 without display: -30 to + 80° C Operating temperature range of data logger S3xxx with display: -30 to + 70° C Accuracy of temperature measurement of internal sensor: ± 0.4° C Accuracy of the S3631 data logger Pt1000 input without probe: ± 0.2° C from -50 do + 100° C ± 0.2% from reading from + 100 to + 260° C ± 0.4% from reading from -90 to -50° C Accuracy of air humidity measurement: ± 2.5% RH from 5 to 95% at 23° C Accuracy of dew point measurement: ± 0.5° C from 30 to 95% RH Resolution of the reading: 0.1° C, 0.1% RH Real time clock: year, leap year, month, day, hour, minute, second Data logging interval: adjustable from 10s to 24h ( 1minute to 24h in low-power mode) Display and alarm refresh: each 10 s ( each 1 minute in low-power mode) Total memory capacity: 32000 temperature, humidity values in noncyclic logging mode Data logging modes: noncyclic - data logging stops after filling the memory cyclic - after filling memory oldest data is overwritten by new Dimensions without connectors: data logger with display 93x64x29mm data logger without display 93x64x26mm Power: Lithium battery 3, 6V, size AA Typical battery life in low-power mode ( 1minute sampling) : 7 years R3120, R3121 6 years S3120, S3121, S3631, S3541 Typical battery life in fast mode ( 10 second sampling) : 3 years R3120, R3121 2.5 years S3120, S3121, S3631, S3541 Battery life in continuous on-line mode with interval 1 minute: reduced to 70% of the above lives in fast mode Battery life in continuous on-line mode with interval 10 second: 1 year Protection of loggers with internal sensors: IP67 - protected against influence of temporary immersion into water, RH+ T sensors are covered with a plastic cover with IP30 protection Protection of S3121, R3121 loggers with cable probe: IP67 - protected against influence of temporary immersion into water, RH+ T sensors are covered with a stainless steel mesh with IP40 protection.
