Top Picks of 2025

#1 - Dwyer Series 2000 Magnehelic® Differential Pressure Gage

A classic that’s earned its reputation for a reason. The Magnehelic® Differential Pressure Gage is the dependable analog workhorse engineers continue to swear by

• Measures low differential pressures in air and non-corrosive gases with precise repeatability.

• Built with a rugged IP67-rated enclosure for real-world durability.

• Ideal for cleanrooms, filter monitoring, HVAC systems, and building pressure control.

In a digital world, the Magnehelic reminds us that sometimes, the simplest solution is the most elegant one.

#2 - Particle Measuring Systems MiniCapt® Mobile Microbial Air Sampler

When air quality validation meets smart design, you get the MiniCapt® Mobile. Built for regulated environments, it makes microbial air sampling cleaner, faster, and easier to manage.

• HEPA-filtered exhaust ensures no risk of cross-contamination.

• ISO 14698-1 compliant, with modern data integrity and tracking features.

• Lightweight, portable, and designed for GMP-grade environments.

In short — it’s the air sampler that actually makes cleanroom monitoring feel clean.

#3 - Additel 760 Series Automatic Handheld Pressure Calibrator

Pressure calibration, but make it portable — and automatic. The Additel 760 Series packs the power of a full calibration bench into one compact handheld device.

• Combines an internal pump, controller, and sensor for a complete all-in-one system.

• Features wireless connectivity (Bluetooth, Wi-Fi, USB) and ISO 17025-accredited calibration.

• Weighs less than 4 lbs, making field calibration actually field-friendly.

Efficiency, accuracy, and mobility — this device redefines “hands-on.”

#4 - Validator AVS (Automated Validation System)

Thermal validation isn’t just about data — it’s about trust. The Validator AVS takes Kaye’s legacy of precision and adds the automation and compliance features that modern life-science facilities expect.

• Wireless sensors with real-time data capture and reporting.

• Designed for pharmaceutical and biotech validation applications.

• Reduces downtime and improves traceability, keeping you always audit-ready.

If validation is your mission, this is the system that ensures you’re always in control — and ahead of schedule.

#5 - FLEX Environmental Monitor 

Setra FLEX™ provides a flexible room environmental control and monitoring solution in a simple-to-use package. More Than a Room Pressure Monitor - The unit supports 3 rooms, monitoring up to 6 parameters for each room. These optional additional parameters can include humidity, temperature, occupancy, particle count, door status, air velocity, and many more environmental factors. 

FLEX's monitor is both a controller and a monitor, with audible and visual alarming on all room parameters. FLEX's monitor enables users to save energy by choosing from two PI control loops and two monitoring sets for any of four room modes, such as occupied and unoccupied.
