We've been running these through our calibration lab for about six months now, and the DSP on this model handles signal curve noticeably better than the older analog units did—especially at the low and high frequency extremes where drift used to creep in, the 1% frequency error spec actually holds up in practice which is pretty much what most clinics need.
Dual independent channels on this one, so you can run air and bone simultaneously without cross-talk issues, and the masking intensity goes from -10dB to 110dB with white noise built in, which saves you from having to add an external noise generator for most standerd assessments.
The LCD display is clear enough but honestly the interface design is what we hear about most from buyers—it's straightforward, you get the test parameters right there with ear selection and step size visible, and the attenuation increments are 5dB with that 1dB error tolerance, better than many units in this price range that don't hold within 2dB after a few months of use.
For high-traffic clinics where you're cycling through 50 patients or so a week, the preheating time under 10 minutes is a real time-saver compared to units that need 20-plus minutes to stabilize, though if your ambient temp runs over 35°C you'll want to check the operating range since it does fine in most environments but no overbuilt cooling here.
2.5% distortion on the air side and under 5% on bone is tighter than what you get from the budget imports that typically advertise 3% air, plus the B71 and TDH39 transducers that come with it are the same ones you'd buy seperately anyway, MOQ is usually 5 units but our company can do single orders if stock allows—just confirm lead time since our batch run is about every 45 days or so.
COA from our in-house HPLC lab goes with each unit, but what a lot of buyers don't think to ask is that we also have teh ISO and CE documentation on file if your compliance folks need it, and the USB port transfers to any standard titration software without proprietary drivers, at least for the builds we've tested on Windows 10 and 11.
We typically require a minimum order of 5 units, but we can sometimes do less depending on stock. Just reach out to us directly.
Standard lead time is around 15-20 working days after order confirmation. If you need it faster, let us know and we'll see what we can do.
Yes, it is CE certified, and we can provide you with the certificate upon request. We also have other quality docs available if your compliance team needs them.
Absolutely. The USB port allows you to transfer test results to a computer for easy record-keeping or printing. No special software is required, but we can share compatible tools if needed.
Store it in a dry, clean environment with temperatures between -10°C and +50°C and humidity below 90%. Avoid direct sunlight or extreme temperatures to keep it working properly.
