Dew Point Transmitter DMT153
Measure dew point so fast, you can improve the future. Enabling a response in minutes rather than hours and the prevention of disruptions. Real-time data is delivered reliably all the way down to true -80 °C (-112 °F) Td/f.
Increase yield by minimizing disruptions
In addition to a radically rapid response, the DMT153 makes it easy to identify trends and prevent costly disruptions from escalating.
The transmitter delivers in situ measurements without complex sampling lines that would slow things down.
Verifiable and consistent despite changing conditions
Anyone who has worked in a dry room, cleanroom, or other critical manufacturing facility knows that conditions are always changing.
Humidity sneaks in from many sources, including people, machines, and even outside weather.
The transmitter's quick response time ensures that all measurement data and trends reflect current conditions, enabling uninterrupted and assured manufacturing.
Beneficial for all applications requiring low dew point levels
- unique research projects
- aerospace and defense
- specialized sensors
- critical compressed air lines
- critical air, nitrogen, argon, helium, and other inert gas lines
- glove boxes and isolators
- pharmaceutical manufacturing, including certain Active Pharmaceutical Ingredients and lithium-based medical devices
- sensitive chemicals, catalysts, or metal powders or other components that might oxidize or hydrate when moisture is present
With the DMT153, you benefit from proven accuracy, fast response time, and full measurement traceability of low dew point measurements.
Integrator? Stay in control, even when the dry room or cleanroom isn't
Your critical manufacturing client expects you to have the answers, solve issues quickly, and have the data to prove what happened.
Combine Vaisala’s dew point probes with Indigo transmitters to deliver reliable, real-time measurements that integrate easily into existing control systems through analog outputs or Modbus over serial or TCP/IP. Access logs, trends, and performance data directly from the Indigo transmitter screen to support commissioning, validation, and troubleshooting.
The Indigo80 handheld indicator enables fast spot checks during installation and service visits when quick confirmation of conditions is needed.
Become the long-term partner for any dry room or cleanroom client.
Perfect for pure gas manufacturers and end-users
Ultra-pure air, nitrogen, argon, helium, and other inert gases
Pure gas manufacturer
As a pure gas manufacturer, your reputation depends on delivering gas that meets strict purity criteria. Moisture is one of the most common impurities, and if it goes undetected, it can lead to rejected cylinders, rework, or customer process interruptions.
Inline, real-time dew point measurement at the bottling line allows you to verify gas quality immediately, without delays, sampling lines, or venting valuable gas.
Pure gas end-user
As an industrial gas consumer, you want to be certain that every cylinder entering your facility meets your quality requirements, not just the supplier documentation.
Fast, traceable dew point measurement enables you to verify incoming cylinders individually and confirm that the gas used in your process is within specification.
This helps prevent quality variation between cylinders, reduces product scrap, and avoids wasting expensive gas due to slow or unreliable measurements.
Production moves fast, and so should the verification of your ultra-dry gases
Lithium compounds, advanced wafer-level processes, and critical components react to or suffer from moisture. Verification must be fast and reliable, waiting hours is not an option.
Vaisala’s Indigo80 Handheld Indicator is the only portable instrument purpose-built for rapid, traceable, reliable dew point verifications down to −80 °C Td/f. It delivers results in minutes.
Connect the Indigo80 handheld to the DMT153 dew point transmitter to measure in-situ without external power, sampling systems, installing new hardware, or managing complex setups.
Use the Indigo80 for spot checks, commissioning, troubleshooting, and process mapping. With traceable measurements and onboard data logging, you can confirm that existing instruments perform correctly, identify optimal installation points, and make confident maintenance and quality decisions.
Still relying on slow or uncertain spot checks?
Discover a faster way to confirm dry conditions in your process.
The optimal solution for extremely dry conditions
With a measurement range of dew point down to true -80 °C (-112 °F) Td/f, the DMT153 is optimal in extremely dry conditions
Radically rapid response in minutes rather than hours
The DMT153 delivers real-time data that enables you to respond
in minutes rather than hours, increasing yield.
Identify trends to prevent disruptions and improve yield
Use trend data to spot any anomalies before issues escalate, and utilize long-term trend data to create a manufacturing profile and optimized trends.
Verifiable and consistent despite changing conditions
The real-time data from the DMT153 is verifiable and consistent despite varying temperatures, outside conditions, equipment heating, or condensation.
Improved connectivity with both digital and analog outputs
The DMT153 is compatible with the Vaisala Indigo platform. It uses the same algorithm and sensor as the predecessor DMT152, minimizing the need for product and system testing.
The DMT153 has improved connectivity with both analog and digital outputs.
High accuracy and low maintenance
The DMT153 has excellent long-term stability. The autocalibration function significantly reduces the long-term drift.
