LEO - Handheld Analyzer - Laboratory all-in-one monitoring
Overview
LEO is a battery operated, handheld analyzer designed to measure CO2, O2 and Temperature (2 channels).
Includes CO2 and O2 sensors, aspiration pump, sampling tube, moisture trap, calibration kit and hard travel case.
Compatible with any incubator on the market.
Samples gas in Diffusion or Aspiration mode. Pump suction rate 100 ml/min. Long term logging.
Micro USB for data download.
CO2 sensor: Non Dispersive InfraRed (NDIR) dual wave length detector with pressure and temperature compensation.
Range: 0-20%; Accuracy ±0.1%
O2 sensor: Fluorescence based optical sensor. Range: 0-20%;
Accuracy ±0.1%.
NOTES
CO2-O2 sensors - Included - Calibrations are traceable to national or international standards and meet ISO 9001 quality management standards
T1 k-type thermocouple - Optional
T2 PT1000 Thermistor - Optional
CO2 - O2 Sensors
The CO2 - O2 sensors are always included in LEO and are contained in a removable part. They feature local memory storing the calibration data. LEO reads the calibration data from the sensors module upon powering on.
- CO2 range: 0-20%
- CO2 accuracy: ± 1.0% of Full scale + 2% reading (at 6% ±0.32%)
- CO2 Sensor: Non Dispersive InfraRed (NDIR) dual wave length detector with pressure and temperature compensation
- O2 range: 0-25%
- O2 accuracy: ±0.1% of Full Scale (at 6% ±0.25%)
- O2 Sensor: Fluorescence based optical sensor
LEO comes with built-in standard intuitive calibration routines for CO2 - O2 sensors. Calibration requires a reference calibration gas or another reliable measuring device.
When needed the sensors module can be extracted from LEO and sent out for calibration to any accredited calibration laboratory.
Gas Sampling
LEO allows sampling gas from the incubator in two ways.
- Diffusion mode: for incubators featuring a gas sampling port with spontaneous outlet
- Aspiration (Pump) mode: for incubators featuring a gas sampling port without spontaneous outlet
In both cases, if gas inside the incubator is humid, prior de-humidification with the MOISTURE TRAP is needed (MOISTURE TRAP is included in LEO).
