Silicon based CARBOCAP sensor technology?
Applied in the laboratory, greenhouse, mushroom roometc.
GM70 hand-held carbon dioxide meter combines theVaisala CARBOCAP? Technology, is a stable andreliable handheld meter. GM70 has a variety of user interface menu selection, a clear backlight LCD display and data recording function chart. GM70 can be selectedaccording to the needs of the user and has a wide range of measurement, measuring the concentration of CO2from low concentration up to 20%.
The preheating time of GM70 is very short, it is particularly suitable for the measurement in the field.GM70 handheld meter can also be used as test VaisalaGM20 and GM220 series carbon dioxide transmittertable. In addition, GM220 series also can use GM70 tocalibration. The user can choose Windows? Software is very simple to handle data recorded in the PC machine.Power saving mode power supply can prolong the time of data records, and can live CO2 data acquisition in the absence of the main power supply.
Flexible measurement
Interchangeable probes
GM70 handheld meter using the probe with the VaisalaGM220 series industrial scale the probe interchange,probe different users can easily change the measuring range of carbon dioxide, a change from low concentration to high concentration, so that the GM70table has use more of A.
One or two probe
GM70 handheld meter can be installed two probe: aprobe can be used for normal field measurement, twoprobe can measure the difference, at the same time two probes can be used as a calibration, a calibration of theprobe to probe calibration calibration is required.
Measurement data and charts
GM70 handheld table shows the concentration of CO2 isppm and% in two ways, that is LCD digital or graphbacklight. With the touch of a button can be converted into digital reading chart.
Users can keep / save function maintains a data and sends it into the holding table memory. Historical chartsshow since the start moment with table data trend. In addition, the chart also easily amplification.
Easy to use instrument
The GM70 handheld has easy to use user interface. The default shortcut keys three: chart, lock / save and record.
When users can easily change the shortcut key function behind.
Data recording and data transmission capabilities
GM70 handheld meter can be recorded in outdoormeasurement data, and can record data by using a power saving mode. The recorded data by selecting the MI7
The 0 link software can be transferred to Windows in?.
Small size and light weight
The GM70 is small, the weight is light, and durable,particularly suitable for harsh environment.
Long term stability
CARBOCAP based on GM70? Sensor has excellent stability and reliability. GM70 calibration cycle suggestedtwo years time
, no maintenance. GM70 handheld meter and the probecan be sent to a service center for calibration.
Field measurements of a wide variety of
The GM70 handheld meter preheating time is very short,it can be used immediately. This characteristic makesGM70 measurement in many field
Very easy to use. Use GM70 handheld meter including laboratory, greenhouse and mushroom room etc.. GM70 handheld meter can also be used for warm pass
Investigation of industry and industrial health.
As a calibration instrument other transmitter
GM70 handheld meter can be used as a calibration ofother CO2 transmitter Vaisala's table, such as GM20 andGM220 series, GM70
A table can also probe calibration of GM220 series.
CARBOCAP excellent stability technology?
The patent technology of CARBOCAP microprocessorbased on GM70 using the Vaisala?, single beam, dual wavelength, NDIR sensor,
It has a solid tuned interference filter.
No mechanical loss
The tuned interference filter is made of silicon materials,eliminating the factors easy mechanical loss, overcomein many other single beam,
Double wavelength sensor production problems.
No sensor aging
CARBOCAP? Sensor due to the elimination of aging sosensor with excellent stability. CARBOCAP? Using thesingle beam
, sample box, CO2 measurement and reference measurement detector. This unifying measurementenvironment, strengthen the long-term and stability of the sensor.
Temperature stability.
