• Data Recording/Processing: Minimum 6 loop programming, calibratable to ±0.2 kPa or ±5% pressure reading, data logging of 50 analog inputs, 8 configurable digital inputs/outputs, sample rates from 1 sample/sec up to 200,000 readings, unit selection (imperial/metric), graphical trending, and exportable data (.csv, .xls, .xlsx).
• Controller Installation/Labor: Requires removal of the existing mercury manometer (to be replaced with a new altitude transducer), disposal of mercury, installation of the new controller, and demonstrated experience retrofitting controllers to these specific chambers.

**For Russell Walk-In Thermal and Humidity Test Chamber (Russell W-series):

• Compatibility: Demonstrated compatibility with Russells Walk-In Thermal and Humidity Test Chambers (Russell W-series).
• Physical Characteristics: Mountable to the test chamber with a touchscreen display.
• Interface/Accessibility: Remote control capability via Lab View, Windows Remote Desktop, or other custom programs.
• Operations: Includes starting parameters, minimum 4 PID control channels, adjustable temperature ramp rate and 1% RH rate of change, temperature control from -80 to 180°C, humidity control from 30% to 95% RH, minimum 15-segment programming, diagnostic system, alarm notifications, and minimum 6 loop programming.
• Data Recording/Processing: Data logging of 50 analog inputs, 8 configurable digital inputs/outputs, measurement accuracy of ±1°C & ±5% RH, sample rates from 1 sample/sec up to 200,000 readings, unit selection (imperial/metric), graphical trending, and exportable data.
• Controller Installation/Labor: Installation of the controller to the chamber, requiring experience retrofitting controllers to these specific chambers.

**Critical Logistical Specifications (Applicable to both):

• Wiring Interface Schematics: Installer must provide engineering drawings/schematics for controller/chamber wiring interfaces.
• Warranty: At least a one-year parts, 90-day labor warranty.

This document is critical for bidders as it details the specific technical and logistical requirements for the controller upgrade project. It defines the performance capabilities, physical and interface needs, data handling, and installation procedures for two distinct chamber types. Bidders must ensure their proposed controllers and services meet all "Minimum Required" specifications to be considered acceptable. Experience with retrofitting these specific Russell chamber models is explicitly required.

Solicitation / RFP / RFQ

This is a combined synopsis/solicitation for commercial products and services, prepared in accordance with FAR Part 12. It constitutes the only solicitation, and no separate written solicitation will be issued. The acquisition is for Controllers for Russell Test Chamber Model RHB-64-705-705-AC and Russells Test Chamber WMD-336-ECMD-4-10-10 for the Defense Health Agency (DHA), Operational Medicine (OPMED) Test Branch.

• The upgrade will facilitate the removal of the chamber's current mercury manometer to conform with mercury elimination guidance.

• Critical Operational Device Specifications (CODS) attachment details specific requirements.

• Contract Type: Firm Fixed Price for controllers and retrofits. Other Direct Costs are Cost No Fee.

• Period of Performance: Not explicitly stated, but delivery is 90 Calendar Days from Date of Award Receipt.

• Estimated Value: Not stated.

• Quote Submission Deadline: 10:00 AM Local Time, 08 June 2026.

• Submission Method: Quotes can be submitted as Microsoft Word, Microsoft Excel, or Adobe PDF attachments to jamie.l.diggs.civ@health.mil and kelly.r.green.civ@health.mil.

• Questions Due: 2:00 PM Local Time, 13 May 2026, via email to jamie.l.diggs.civ@health.mil and kelly.r.green.civ@health.mil (Subject: HT9427-26-Q-E007).

• Evaluation Factors: Award will be made on a competitive best value basis using "best value tradeoff" among price and non-price factors. The factors, in descending order of importance, are: Technical Capabilities/Specifications, Past Performance, and Price. Past Performance is more important than Price. Non-price factors are collectively more important than price.

• This acquisition is set-aside for small business concerns.

• The solicitation incorporates provisions and clauses by reference, accessible at www.acquisition.gov.

• Required attachments include: Attachment 1 - CODS and Attachment 2 - Ratings.

• Offerors must be registered in the System for Award Management (SAM) database at time of award.

Form / Attachment / Pricing Sheet

This document, "Attachment 2 - Ratings," provides the standard definitions for adjectival ratings used in evaluating proposals under the solicitation. It outlines the criteria for both Technical Capabilities/Specifications and Past Performance.

Evaluation Factor I – Technical Capabilities/Specifications:

• Outstanding: Exceptional approach, understanding, multiple strengths, low risk.
• Good: Thorough approach, understanding, at least one strength, low to moderate risk.
• Acceptable: Meets requirements, adequate approach, understanding, no worse than moderate risk.
• Marginal: Inadequate approach, understanding, or high risk.
• Unacceptable: Does not meet requirements, deficiencies, unawardable, or unacceptably high risk.

Evaluation Factor II – Past Performance:

• Acceptable: Reasonable expectation of successful performance based on record, or performance record is unknown.
• Unacceptable: No reasonable expectation of successful performance based on record.

Note: For past performance, a "neutral" rating (when information is unavailable or sparse) is considered acceptable.

This attachment is crucial for bidders as it defines the rating scales used to evaluate their technical approach and past performance. Understanding these definitions will help bidders tailor their proposals to meet or exceed the government's expectations and maximize their chances of a favorable rating.
