Calibration is the backbone of environmental monitoring — but for too long, field technicians have been stuck crouching over heavy equipment, squinting at faint displays, and hauling bulky hardware from site to site. Accuracy shouldn't require a workout.
The Tisch Environmental FloCal-30 is a NIST-traceable flow calibrator built specifically for ambient air sampling in the field. With a range of 0.5–30 SLPM and live Bluetooth mirroring to your phone, it delivers ±1% accuracy whether you're on a rooftop, inside a mobile trailer, or standing in −30°C cold.
One Calibrator. Every Sampler.
The FloCal-30 covers the full range needed for every standard FRM and FEM ambient air sampler — low-volume to high-volume — in a single pocket-sized device. Its sunlight-readable 2.3" TFT LCD (320×240) shows everything on one screen with no menus to navigate:
- Volumetric and Standard Flow (LPM and SLPM)
- Relative Humidity (0–100%, ±1.5% accuracy)
- Temperature (±0.1°C accuracy)
- Barometric Pressure (400–900 mmHg, ±3 mmHg)
| Parameter | Range | Accuracy / Notes |
|---|---|---|
| Flow Range | 0.5–30 SLPM | ±1% (−20°C to 60°C) |
| Flow Resolution | 0.01 LPM | — |
| Barometric Pressure | 400–900 mmHg | ±3 mmHg |
| Temperature | −30°C to 60°C operating | ±0.1°C |
| Relative Humidity | 0–100% RH, non-condensing | ±1.5% |
| Battery | 18 hrs continuous | USB-C, 4.5 hr recharge |
| Weight / Size | 15.1 oz (428 g) | 2.7" × 4.7" × 1.3" |
Walk Away from the Sampler — For Real
One of the most frustrating parts of field calibration is being physically tethered to equipment. The FloCal-30 solves this with Bluetooth Low Energy (BLE) that mirrors the device display directly to your phone in real time — same readings, same units. Step away from the sampler, move around the trailer, or simply stand upright.
The companion app is available on both iOS and Android with zero setup or account creation. Open the app, tap your FloCal-30, and you're live.
Why Technicians Are Switching
Every spec traces back to a real field problem:
18-Hour Battery. USB-C Charging.
The FloCal-30 runs on an internal 7.4 Wh lithium-ion battery rated for 18 hours of continuous use. When it's time to recharge, a standard USB-C cable tops it off in 4.5 hours — no proprietary chargers, no hunting for the right cable.
