DryCal Defender & Met Lab Flow Calibrators

Bios Defender 510 and Defender 520 Volumetric Flow Calibrators

Bios Defender 510 and 520 calibrators are true primary flow meters and immune to flow source pulsation without the need for in-line dampers. The Defender Series is more accurate and more repeatable than the older DryCal DC-Lite and DryCal DC-2. Volumetric flow units may be set to ml, l, cc, or cf. The Defender calibrators can be set to take individual readings, continuous hands-free readings, or set to read in user selectable time intervals. They can also be set to include up to one hundred readings in a group average.

Bios Defender 530 Calibrators with Volumetric &Standardized Flow

The Bios Defender 530, with the ability to take both volumetric and standardized readings, is the latest addition to the popular Defender 510 and 520 line of Bios DryCal primary flow calibrators. Automatic correction of readings for temperature and pressure, rather than merely recording of ambient conditions, is essential for many applications.

Bios Optimizer Software CD and Computer Data Entry Screen

Optimizer Collect Software

Each Defender instrument is shipped with Optimizer Collect Light datalogging software which allows for automatic recording and graphing of flow measurements. The full Optimizer Collect software is available as a factory option or may be added later as a field upgrade, and allows the user to not only capture, but secure, organize, search and present data.

Fully automated multi-flow tests can be easily performed for the analog mass flow controllers (MFC), analog mass flow meters (MFM) and other flow devices. With the Excel interface, users can customize data capture and data reporting for any flow device including rotameters, turbine meters and wet/dry gas meters

Bios Definer™ 220 Primary Gas Flow Calibrator
for Standardized Flow Verification

The Definer 220 allows users to verify gas flow rates, in the field or in the lab, to an accuracy of ±1% percent of reading, including temperature and pressure compensation. The Definer 220 is a field-hardy primary flow meter that is NIST traceable.

BIOS DryCal ML-500^® Primary Gas Flow Calibrator

Flow and mass-flow calibrator with less than 0.5% error, corrects mass flow to Standard Temperature and Pressure, continuous readout, simple push-button operation, NIST traceable calibration. Covers 5.0 sccm to 50 L/min with 3 field interchangeable flow-cells. Uses BIOS's dry-piston technology.

Bios DryCal ML-800^® Primary Gas Flow Calibrator

The high-speed, mercury-free, Bios DryCal ML-800 is the most accurate piston prover, with a ±0.15% accuracy of reading, not of full-scale. The Bios DryCal ML-800 is available with five interchangeable flow cells to cover an ample measuring range, from 5 cc per minute to 50 liters per minute. Flows are automatically corrected to standardized temperature and pressure conditions using precision sensors within both the gas flow stream and the base unit for the highest degree of accuracy.

                          Auto Calibration Range Selection

  Bios DryCal ML-1 Met Lab One^® Primary Gas Flow Calibrator

The newest addition to the Met Lab series features 3 flow tubes in a single portable unit. Auto-ranging from 5 to 50,000 sccm with 0.15% accuracy. Designed for use with corrosive gases.

Bios Definer 1020 - 500 SLM Primary Piston Prover

The Bios DryCal Definer 1020 Met Lab is a compact but powerful calibrator with a flow range of from 5 to 500 liters per minute - up to ten times the volume of any other piston prover on the market! The portability of this new model, which weighs in at a feathery 90 lbs. is a dramatic and welcome improvement over the cumbersome bell provers labs have used in the past.

Bios Integrator™ 110 - Met Lab Command & Control Module

Automation can mean greater efficiency & enhanced accuracy – especially in the calibration of mass flow devices. The Integrator™ 110 is a command, control and readout system that connects with mass flow devices and our Met Lab® Series of primary piston provers to semi- or fully-automate As-Found (pre) and As-Left (post) flow verifications and complex, multi-setpoint MFC and MFM calibrations. The Integrator 110 can be integrated with both the Met Lab Series and Optimizer Collect software.

Bios Gas Flow Bench for General Applications

How Good Is Your Calibration Flow Source?

Bios Gas Flow Bench

Your calibration results are only as good as your calibration flow source. The Bios Gas Flow Benches offer practical engineered solutions for calibration of gas flow measurement devices configured to provide the stable flow critical to the calibration process. Bios configurations use different components to connect the gas source, regulate pressure, control the flow, and direct the flow to a specific device being calibrated against a DryCal® standard. The Bios Flow Benches are pre-configured for specific applications. They are available in different configurations.

Bios Definer 110 Series - Flow Transfer Standards

The Bios Definer 110 is a compact indestructible EPA Flow Transfer Standard. The Definer 110 is small and lightweight, making it at home in the field, where rough handling is the norm. It is a direct replacement to fragile, glass-style orifice calibrators used on PM2.5, PM10 and TEOM air samplers. The compact, durable orifice is designed to fit directly on an air sampler with a standard 1.25 inches OD inlet tube and the pressure drop across the orifice is measured with a digital manometer.
