Introducing the RapidDuo™
Man-Tech is pleased to announce the release of the RapidDuo™. The RapidDuo enables rapid multi-parameter analysis from a single sample. The RapidDuo is the HIGH SPEED version of Man-Tech’s PC-Titrate TitraSip System.
Analyze pH, conductivity, alkalinity, fluoride and turbidity
in 4 minutes or less, total cycle time!

Analyze up to 197 samples, unattended, in a single batch!
Still, the largest capacity system on the market, and now even FASTER.
Man-Tech delivered Multi-Parameter Solutions to the Environmental Industry 10 years ago, meeting the requirements of unattended analysis. In today’s ever changing market, Environmental Laboratories are challenged to deliver results faster and Man-Tech has the solution, once again with the RapidDuo.
Key Features and Benefits of the Man-Tech RapidDuo™:
- Utilizes US EPA ETV verified TitraSip SA technology
- Backward Compatible. Current TitraSip end-users may upgrade and cut the analysis time in half
- Rapidly generated results are accurate and precise
- Available configurations include stand alone, near-line or with the AutoMax sampler
- Galvanic electrode separation allows for simultaneous and separate analyses from the same sample
- IntelliRinse system ensures system and probes are clean before moving to the next sample
- Generates results for your clients sooner
- Durable, reliable
- Delivers results that stand the test of time
- Rinse the probes, analysis vessels and all pipetting lines.
- Move to the sample and triple dip for the conductivity measurement (conductivity is automatically separated from the pH and fluoride electrodes).
- While measuring conductivity, simultaneously pipet sample aliquots into the alkalinity analysis vessel and fluoride analysis vessel. TISAB is also simultaneously added to the fluoride analysis vessel.
- While measuring the pH and titrating for alkalinity, simultaneously stabilize and measure the fluoride concentration.
- Move the sampler arm to the rinse station.
- Simultaneously drain both analysis vessels and rinse the entire system using Man-Tech’s dynamic IntelliRinse™.
- For the next sample, repeat steps 2 – 7.
- Total cycle time for alkalinities 500ppm or less, 3 minutes or less!
- Enables running real, revenue generating samples sooner
- Increases the capacity of the AutoMax sampler for real, revenue generating samples
- Increases profitability
- Analyse turbidity and/or color from the same sample!
- For a complete list of approved methods capabilities, please request the Approved Methods List
- Add the PC-BOD
- BOD by Day, Titrate by Night
How Does the RapidDuo Work?
The key to the success and development of the RapidDuo is Man-Tech’s innovative TitraSip System and the PC-Titrate software. The PC-Titrate software allows the control of 2 or more TitraSip modules in a single system. Most functions and analyses occur simultaneously which is the heart of the FAST analysis.
In the case of a RapidDuo for conductivity, pH, alkalinity and fluoride, this is schedule of operation and analyses.
