TSI 8380-H Portable Remote Readout Unit & Air Flow Hood Stand

Overview

The TSI 8380-H Portable Remote Readout Unit & Air Flow Hood Stand is an integrated hardware solution engineered to enhance field efficiency and measurement integrity during HVAC airflow verification, commissioning, and indoor air quality (IAQ) assessments. Designed exclusively for use with the TSI 8380 AccuBalance™ Air Flow Capture Hood, this system decouples operator proximity from measurement execution—enabling real-time remote acquisition, visualization, and documentation of volumetric airflow (CFM or L/s), static pressure differential (in. w.c. or Pa), temperature, and relative humidity. The readout unit operates on a Bluetooth 4.0+ wireless protocol compliant with IEEE 802.15.1, supporting bidirectional communication at distances up to 30.5 meters in typical indoor environments with line-of-sight conditions. Its core architecture adheres to principles of traceable metrology: all sensor inputs are conditioned through TSI’s proprietary analog-to-digital conversion circuitry, ensuring stable signal integrity and minimizing drift under variable thermal loads.

Key Features

• Portable Android-based remote readout unit preloaded with LogDat™ Mobile software—supports real-time display of one primary parameter (e.g., airflow) and up to four secondary parameters (e.g., velocity, temperature, RH, differential pressure)
• Configurable analog-style digital gauge interface with user-adjustable scaling and color-coded thresholds for rapid visual interpretation
• In-field data capture capabilities including timestamped screenshots, voice annotations, and embedded photographic documentation directly linked to Test ID records
• Local on-device storage of test sessions with export-ready CSV/Excel-compatible output; no cloud dependency required for basic operation
• Modular air flow hood stand featuring dual-stage telescoping aluminum extension rods (secured by stainless-steel knurled screws), enabling precise vertical positioning from 1.2 m to 3.0 m
• Industrial-grade polyurethane casters with locking brakes for smooth maneuverability across carpeted, tiled, or concrete surfaces—eliminating ladder dependency for ceiling diffuser and grille measurements up to 4 m height
• Integrated carry system: padded, shoulder-strap-equipped transport case designed for simultaneous storage of readout tablet, hood, tubing, and calibration certificate

Sample Compatibility & Compliance

The 8380-H system maintains full mechanical and electrical interoperability only with the TSI 8380 AccuBalance™ Air Flow Capture Hood and its factory-calibrated internal micro-manometer. It does not support third-party hoods or alternate pressure sensors. All airflow calculations comply with ASHRAE Standard 111–2013 (Practice for Instrumentation in Buildings) and ANSI/ASHRAE Guideline 1–2021 (Standard Method of Test for Air Velocity and Volume Flow Rate). The Bluetooth radio module meets FCC Part 15 Subpart C and IC RSS-247 regulatory requirements for unlicensed short-range devices. While the LogDat™ software itself is not FDA 21 CFR Part 11-compliant out-of-the-box, audit-trail functionality—including user login logs, timestamped edits, and immutable Test ID metadata—can be enabled per site-specific validation protocols aligned with ISO/IEC 17025:2017 Clause 7.7 (Results Reporting) and GLP Annex III (Computerized Systems).

Software & Data Management

LogDat™ Mobile provides a deterministic data acquisition environment optimized for field technicians. Each Test ID includes mandatory fields for location tag, operator ID, date/time stamp (GPS-assisted when enabled), and optional multimedia attachments. Statistical summaries—mean, standard deviation, min/max, and coefficient of variation—are auto-generated per test sequence. Trend plots (time-series graphs of airflow vs. duration) are rendered natively using HTML5 Canvas without external dependencies. Data exports support UTF-8 encoding and retain all metadata headers, facilitating direct import into LIMS platforms or QA/QC dashboards. For enterprise deployment, TSI offers LogDat™ Desktop (Windows-based) for batch post-processing, report generation (PDF/HTML), and integration with Microsoft SQL Server databases under validated configurations.

Applications

This system is routinely deployed in HVAC balancing and TAB (Testing, Adjusting, and Balancing) workflows per NEBB Procedural Standards, as well as in LEED EQ Credit 1 (Outdoor Air Delivery Monitoring) verification audits. Common use cases include: quantitative assessment of VAV box minimum airflow settings; verification of exhaust hood face velocities in laboratory safety compliance (per ANSI Z9.5); residential duct leakage testing support; and periodic re-commissioning of healthcare facility air handling units (AHUs) under FGI Guidelines. Its portability and ladder-free operation significantly reduce occupational risk exposure during high-ceiling inspections in warehouses, cleanrooms, and atrium spaces.

FAQ

Can the 8380-H readout unit operate without the LogDat™ app?
Yes—when used in standalone mode, the 8380-H stand functions purely as a mechanical positioning aid; the 8380 hood’s built-in display remains fully operational, and pressure readings can be taken directly via its internal manometer using the included 8-ft tubing.
Is firmware update capability supported over-the-air?
Firmware updates require connection to a Windows PC running TSI’s official Device Configuration Utility; OTA updates are not implemented due to regulatory constraints on measurement-critical embedded code revisions.
Does the stand accommodate non-TSI air flow hoods?
No—the mounting interface, weight distribution, and center-of-gravity alignment are engineered specifically for the TSI 8380 hood geometry and mass profile; retrofitting is not recommended or supported.
What is the battery life of the Android tablet when running LogDat™ continuously?
Typical runtime exceeds 6 hours under continuous Bluetooth polling and screen-on conditions; extended-life models with hot-swappable batteries are available as OEM-configured options.
Are calibration certificates provided with the stand or readout unit?
Calibration applies solely to the 8380 hood and its internal pressure transducers; the stand and readout unit are mechanical/electronic components not subject to metrological calibration—certificates reference NIST-traceable calibration of the parent instrument only.
