PORTABLE AIR CHECKER for TOYOTA / TSUDAKOMA AJL (TR-7800AC)
Demonstration video of TR-7800AC Portable Air Checker
The TR-7800AC Portable Air Checker for Toyota/Tsudakoma AJL contributes to the improved quality control of your reeds based on comparison of air flow graphs.
Continuous Measurement
One of the advantages of the TR-7800AC is continuous and digital measurement (1mm pitch) of air flow. Rather than manual measurement and checking of just a few points, a comprehensive air flow status of the reed is provided. Location of unusual air flow along the reeds can be identified on the graph generated by the encoder behind the unit.
On-loom Measurement
The TR-7800AC enables you to measure air flow on-loom with only a minimum preparation of your Toyota/Tsudakoma AJL. (move the reed to the vertical position, loosen the warp yarns, lift and fix the reed)
Easy data input, graph, and comparison with past data
After installation of software, air flow data can be imported from the TR-7800AC to your personal computer through a USB cable. The air flow data can be quickly and easily converted to a graph format. Those data can be stored according to your reed serial numbers, so comparison with past data of the same reed is feasible (10 measurements per serial number can be stored in the PC file).

Air flow of new reeds is the best. Air flow that is too high may cause the weft to fly out of the tunnel. Fluctuating air flow may prevent the stable flight of the weft. Air flow that is too low may cause unexpected weft flight anomalies.
Other Features of the TR-7800AC
– Calibration before every measurement can ensure accuracy of your air flow data.
– Real time checking of air flow on the LCD of the TR-7800AC during measurement is also feasible. The graph can be displayed on the LCD, too.
– PDF output of the graph is possible. This makes it easy to distribute results amongst necessary co-workers.
– Encoder position is adjustable depending on the outer height of your Toyota/Tsudakoma AJL reeds.
– cmAq and 10-3 kgf/cm2 are the employed units of air flow.
– Standard AA type batteries are applied. Low battery charge is indicated on the LCD screen. Data is not deleted by battery replacement.
TR recommends a combination of the TR-7800AC and the TR Reed Cleaner (TR-7600RC: On-loom Reed Cleaner or TR510: Ultrasonic Reed Cleaning Machine) for quality control of your reeds:
