Kanomax 1590-0C Multi-Point Thermal Anemometer System

Overview

The Kanomax 1590-0C Multi-Point Thermal Anemometer System is a modular, high-channel-count environmental monitoring platform engineered for precision measurement of air velocity, temperature, and relative humidity across large-scale or spatially complex environments. Based on constant-temperature anemometry (CTA), the system utilizes thermistor- or hot-film-based probes to detect convective heat loss from heated sensing elements — a principle directly correlated to local airflow velocity with high linearity and repeatability. Unlike single-point handheld instruments, the 1590-0C architecture supports distributed sensing networks, enabling synchronized, time-aligned acquisition across up to 144 independent measurement points. Its design targets applications requiring spatial mapping of HVAC performance, cleanroom validation, laminar flow verification, ventilation efficiency assessment, and industrial process airflow monitoring — all under ISO 14644, ISO 16813, ASHRAE Standard 111, and EU GMP Annex 1 compliant workflows.

Key Features

• Modular scalability: One 1590-0C main unit connects up to 12 Model 1591-0C measurement modules; each module supports 12 interchangeable probes — enabling configurations from 1 to 144 channels.
• 15 certified probe variants: Including directional and omnidirectional thermal anemometers; standard, ultra-compact, and high-temperature (up to 120 °C) models; combined vane/thermistor/hygrometer probes for simultaneous velocity, temperature, and RH measurement.
• High-resolution low-velocity detection: Minimum measurable airspeed of 0.01 m/s with sub-second response (t₉₀ ≤ 1 s at 1 m/s, ambient conditions), critical for low-turbulence environments such as pharmaceutical isolators or semiconductor tool enclosures.
• Integrated 7-inch capacitive touchscreen interface: Enables standalone operation — real-time data visualization, probe calibration status review, channel configuration, and CSV export without external PC connection.
• Dual analog output capability: Each 1592-0C analog output module provides configurable 0–5 V or 4–20 mA signals per channel. Up to 12 modules support full 144-channel analog replication for integration into PLCs, DCS systems, or legacy SCADA infrastructure.
• Robust environmental rating: Main unit and modules rated for operation at 5–40 °C and 0–85 %RH (non-condensing); probe-specific extended ranges validated per ASTM E741 and ISO 7726 protocols.

Sample Compatibility & Compliance

The 1590-0C system accommodates diverse sampling geometries through its mechanically optimized probe portfolio: ultra-slim probes (e.g., 0976-03, Ø1.6 mm) enable insertion into ductwork access ports or micro-environments; rigid directional probes (0972-00) ensure consistent angular alignment in ISO Class 5–8 cleanrooms; high-temp probes (0976-07/13) maintain NIST-traceable accuracy during oven or sterilizer validation. All probes undergo individual factory calibration against NIST-traceable reference standards, with calibration certificates available per probe serial number. The system supports audit-ready data integrity via timestamped CSV logging (ISO/IEC 17025-compliant metadata), and optional software-configurable audit trails align with FDA 21 CFR Part 11 requirements when used with validated Windows 10 host systems.

Software & Data Management

Kanomax’s proprietary Windows 10-compatible software (v3.x+) enables multi-language UI (English, Japanese, Chinese), real-time 144-channel waveform plotting, statistical analysis (min/max/avg), and customizable alarm thresholds. Data is stored natively in UTF-8 CSV format — compatible with MATLAB, Python pandas, JMP, and LIMS platforms. Each measurement record includes probe ID, calibration date, timestamp (ms resolution), raw sensor values, and user-defined location tags. Internal 8 GB flash memory retains ≥24,500 readings per module (1,000 per channel), supporting unattended logging over extended campaigns. USB and Gigabit Ethernet interfaces provide redundant connectivity options; LAN mode supports remote monitoring via static IP or DHCP in enterprise network environments.

Applications

• HVAC commissioning & TAB (Testing, Adjusting, Balancing): Simultaneous capture of supply/return/exhaust velocities across multiple grilles or diffusers.
• Cleanroom certification (ISO 14644-3): Uniformity mapping of unidirectional airflow velocity profiles at working height and filter face.
• Pharmaceutical facility qualification: Airflow visualization in RABS, isolators, and lyophilizer chambers per EU GMP Annex 1 Section 4.37.
• Automotive cabin airflow analysis: Multi-zone thermal comfort assessment using compact probes embedded in seat vents or dash registers.
• Industrial furnace & dryer validation: High-temperature airflow profiling using 120 °C-rated probes with integrated temperature compensation.
• Academic aerodynamics research: Low-speed boundary layer studies requiring synchronized, high-density point measurements.

FAQ

What is the maximum number of simultaneous measurement points supported?
The system supports up to 144 channels: one 1590-0C main unit + twelve 1591-0C modules × twelve probes per module.
Can probes be calibrated individually, and are calibration certificates provided?
Yes — each probe is factory-calibrated against NIST-traceable references; individual calibration certificates (including uncertainty budgets) are supplied with each probe.
Does the system comply with FDA 21 CFR Part 11 for electronic records?
When deployed with validated Windows 10 hosts and configured audit trail logging, the software meets Part 11 requirements for signature, retention, and change control.
Is analog output configurable per channel?
Yes — each channel on a 1592-0C module can be independently assigned 0–5 V or 4–20 mA output scaling, with user-defined engineering units.
What is the minimum measurable air velocity, and under what conditions is it guaranteed?
0.01 m/s is achievable with probes 0972-00, 0975-00, and 0975-21 under stable ambient conditions (23 °C, 50 %RH), per Kanomax Technical Bulletin TB-1590-01.
