Digital Audiometry Machine
Two-channel diagnostic audiometer — pure tone, speech and free field.

Model: NidhiFlow 814 · Brand: NidhiFlow
Weight-based digital uroflowmeter with printer and auto-start.
The NidhiFlow 814 is a printer-based digital uroflowmetry system for urology OPDs, hospitals and urodynamics departments. A digitally controlled, weight-based piezoresistive transducer measures voided volume and flow rate in real time, producing a printed flow curve with Qmax, average flow, voided volume and voiding time.
It handles up to 2000 mL per void and peak flows up to 50 mL/s, detects Qmax within one second and offers auto-start, auto-print and beaker-full alarms. On-site auto-calibration, a rust-free moulded ABS body and a light 0.9 kg module make it practical for busy clinics.
Typical uses include pre-TURP assessment, suspected urethral stricture, BPH follow-up and routine paediatric to geriatric evaluation. RS Enterprises supplies the NidhiFlow 814 with installation, staff training and consumables.
