A Capacitive Screen Where the Keypad Used to Be
A Capacitive Screen Where the Keypad Used to Be
Touchscreens on cleanroom instruments usually fail for one reason: gloves. The H240 uses a capacitive panel tuned for nitrile, so the same display that shows the trend graph can be driven without a stylus or a membrane keypad that fills with particles.
- Two modes — particle count for classification, mass concentration for trend work, switched in one tap.
- Six channels plus mass — 0.3 to 10 μm alongside PM2.5 and PM10.
- Live trend — the sample is plotted second by second while it runs, so an obstruction shows up as a flat line immediately.
The report is generated on board as a PDF. No laptop, no proprietary software, no waiting until the end of the day.
Classification and Trend Work in One Visit
Classification and Trend Work in One Visit
A single visit usually has two jobs: prove the room is in class, and understand whether it is drifting. The H240 does both without changing instrument or reconfiguring units.
- Flow — 2.83 L/min ± 5%, the ISO 14644-1 working rate.
- Typical use — cleanroom classification, trend monitoring, environmental monitoring and technical service call-outs.
- Battery — 4,400 mAh, eight hours, which covers a full classification day on one charge.
Records carry room, operator and batch fields, so the PDF that leaves the instrument is already filed under the right heading.
Bluetooth Export Without Leaving the Room
Bluetooth Export Without Leaving the Room
100,000 records, exported over USB or Bluetooth as CSV or PDF. The Bluetooth path exists for the case where the instrument is inside the cleanroom and the laptop is not.
- Display — 3.5″ capacitive, 480 × 320, gloved-hand operation.
- Body — ABS + PC, IP54, 205 × 105 × 60 mm at 0.70 kg.
- Standards — ISO 14644-1, EU GMP Annex 1, ISO 21501-4; calibration with PSL spheres.
Eight hours of battery and a PDF generator on board means a service engineer can leave the van with nothing but the instrument.
FAQ
With nitrile gloves, yes — the panel is tuned for it. That is the reason this model exists. A membrane keypad fills with particles and a resistive screen needs a stylus; a capacitive panel that responds through a glove does neither.
Particle count and mass concentration. Count mode gives you six channels from 0.3 to 10 μm for classification; mass mode gives PM2.5 and PM10 for trend work. Switching is one tap, not a reconfiguration.
Yes. The PDF is generated on board and leaves over USB or Bluetooth. The record already carries room, operator and batch fields, so the file is filed under the right heading without anyone editing it afterwards.
The count is plotted second by second while the sample runs. If the probe is obstructed the line goes flat, and you see it during the run rather than in the report three days later.
Eight hours from a 4,400 mAh pack, which covers a full classification day on one charge. Charging goes through the instrument from a normal mains outlet.
Because the interface moved from a keypad to a touchscreen, and a touchscreen needs the space. The 3.5″ panel at 480 × 320 is large enough for the trend graph and the counts on the same page, which the 2.8″ display could not do.
