Special specifications

 

In addition to the standard model, it is possible to specify constituents, and if the small flow rate set, communication set, or NOx-NO switching solenoid valve set is provided.
Measurement
components
1 constituent (NOx) or 2 constituents (NOx, O2) (*5)
O2 cannot be measured if small flow rate set is selected. See small flow rate set page.
NO and NO2 can be measured as well as NOx if NOx-NO switching solenoid valve set is selected.
See NOx-NO switching solenoid valve set page.
Measurement
range
NOx: 0-25/50/100/250/500/1000/2500/4000 ppm
O2: 0-5/10/25vol%
NOx measurement range differs if small flow rate set is selected.
See small flow rate set page.
Small flow rate set Not fitted Fitted
Response time (*2) NOx: Approx. 20/30/60 sec
       (Switching is configurable.)
O2: Approx. 30/60 sec
       (Switching is configurable.)

Not equipped Measurement data stored in the internal memory of the analyzer can be output to USB flash drives in CSV file format; can also be output to computer via Wi-Fi or LAN cable connection.
NOx-NO switching solenoid valve set Not fitted Fitted
Measurement components NOx NOx, NO, NO2 (*1)
This special accessory switches the flow path inside the analyzer between a path that flows through the converter (NOx flow path) and one that does not flow through the converter (NO path). The switch cycle is selectable from auto (configurable from 1 to 99 minutes), manual, and fixed. If there is significant variation over time in concentrations of NOx, NO, or NO2 relative to the switching cycle, NO2 concentration measurement accuracy diminishes.
Basic specifications are as follows.

Basic specifications

Measurement principle NOx: Atmospheric pressure chemiluminescence method
O2: Limiting current type zirconia method
Repeatability Within ±0.5% of full scale
Zero drift Within ±1% of full scale per day (25 ppm range: within ±1.5% of full scale per day)
Span drift Within ±1.5% of full scale
Linearity Within ±2% of full scale
 
The following specifications are the same as for the standard model.
Display, transmission output, permissible ambient temperature, permissible ambient humidity, power requirements, dimensions, weight (body), sample gas conditions, external signal input.
*1: NO2 is measured by calculation (NOx-NO).
*2: Time that indicates 90% response from gas flowing from sample gas inlet (flowing gas switching time + electrical system response time). With Type 2, this will be the response when NOx-NO switching is fixed.
*3: Check the Shimadzu website for smart devices and USB flash drives for which operation has been confirmed.
*4: Permissible ambient temperature and humidity are indicated by the shaded part of the figure.
*5: Sample gas conditions and coexisting gases are summarized below. Please contact your Shimadzu representative if the conditions are not satisfied.
