The required parameters for smoke and dust are displayed on the same screen, such as the number of sampling holes, the current sampling hole sequence number, the number of sampling measurement points, the current measurement point sequence number, the measurement point position size, and its countdown time. Make sampling, point and hole replacement more accurate and reliable, and enable automatic constant velocity tracking or constant current sampling.
When sampling with low flow rate and high negative pressure of flue gas, a 12mm sampling nozzle is used. When the negative pressure in front of the sampling tube is -20kPa, the tracking sampling flow rate is greater than or equal to 50 L/min.
The instrument comes with 600 sets of data memory, and data is not lost after power failure. It can continue to work after power on. Specific data may include parameter settings before sampling, sampling date, time, measurement parameters, sampling category, sampling method (such as constant velocity or constant current), and so on.
Product advantages
- Anti static and anti magnetic field.
- Strong air pump: can maintain high flow working state under high negative pressure conditions: the maximum negative pressure is greater than 65kPa, and the no-load flow rate is greater than 85L/min. When using a 12mm sampling nozzle and a negative pressure of -20 kPa in front of the sampling tube, the tracking sampling flow rate is greater than or equal to 50 L/min.
- Titanium alloy material combination sampling probe, lightweight and durable.
- External gas cylinder, compact and tidy, easy to use.
- Comes with built-in memory, data is not lost in case of power failure.
- Equipped with a printer, data can be printed on-site.
- Lightweight and aesthetically pleasing, ergonomically designed, with reasonable weight distribution, easy to carry.
