Measure the environment. Inform decisions.
MANN-INNOVATECH AND SERVICES designs, deploys, and interprets environmental measurement systems — air, water, soil — for Cameroonian and international decision-makers who need reliable data to act on.
Air quality · Water quality · Soil quality — example
- Based in Yaoundé, Cameroon
- Applied environmental instrumentation
- Support in French and English
Capabilities shown here are confirmed on a per-project basis.
Four domains, one measurement discipline
Air, water, soil, and food each demand their own sensors, protocols, and constraints. We make them legible for decision-making.
Air quality
An industrial site, a school, a health facility, or a local authority needs to understand air quality — indoor or emitted — without measurement data to ground the picture.
- Possible deliverables
- Timestamped measurement log over the monitoring period
- Who it's for
- Industrial sites and impacted zones
Water quality
A water operator, local authority, or site needs to track the quality of a resource or discharge point over time, without a measurement system in place.
- Possible deliverables
- Measurement log per monitoring point
- Who it's for
- Water and sanitation operators
Soil quality
A construction site, quarry, or developer needs an initial soil diagnostic before a decision, without field measurement in hand.
- Possible deliverables
- Field measurement log per diagnosed point
- Who it's for
- Construction, mining and quarrying
Food quality
A food processor, farm operator, or quality controller needs a fast, objective check of raw materials or products, without an on-site laboratory.
- Possible deliverables
- Measurement log per batch or control point
- Who it's for
- Food processors and agri-food operators
Our field instruments
Devices our team actually deploys on site — not stock illustrations.
WaterPocket multiparameter water tester
Water quality, read in seconds, right on site.
This pocket tester reads pH, conductivity, salinity, and redox potential directly at the water point, with no lab turnaround needed. It's the type of device our team used during the Edéa site diagnostic to characterize water on a site under construction before it went into operation.
- pH
- Conductivité (EC)
- Salinité
- ORP
- Résistivité
- H₂
Soil3-in-1 soil analyzer
An instant first soil read — no reagents, no waiting.
Pushed straight into the ground, this analyzer reads soil moisture, light exposure, and pH on the spot: a reliable first read for a developer, farmer, or engineering consultancy before any siting or planting decision.
- Humidité
- Luminosité
- pH
Soil7-in-1 digital soil analyzer (NPK)
Nitrogen, phosphorus, potassium: soil fertility, quantified on site.
This handheld analyzer measures seven soil parameters — moisture, temperature, pH, electrical conductivity, and the three macronutrients nitrogen, phosphorus, potassium — supporting an agronomic diagnostic or pre-planting quality check without a laboratory analysis cycle.
- Humidité
- Température
- pH
- Conductivité (EC)
- Azote (N)
- Phosphore (P)
- Potassium (K)
AirPM1 / PM2.5 / PM10 fine-particle monitor
Indoor air quality, visible around the clock.
This monitor continuously displays fine particulates (PM1, PM2.5, PM10), temperature, and humidity: useful for a facility manager, school, or health center that wants to track indoor air without heavy installation.
- PM1
- PM2,5
- PM10
- Température
- Humidité
AirCO / CO2 / VOC / HCHO air quality detector
CO, CO2, formaldehyde: the invisible pollutants, finally visible.
With a live-calculated air quality index, this device tracks carbon monoxide, carbon dioxide, volatile organic compounds, and formaldehyde: key indicators for an office, workshop, or newly built home where material off-gassing is a concern.
- CO
- CO2
- COV (TVOC)
- HCHO
- AQI
AirPortable 4-gas detector
Gas safety, on your field team's wrist.
Built for high-risk environments, this detector continuously monitors explosivity (%LEL), oxygen, hydrogen sulfide, and carbon monoxide: essential safety gear before any confined-space or industrial-site intervention.
- EX (%LEL)
- O2
- H2S
- CO
Instrumentation & data
From sensor to report, every link in the measurement chain is built to hold up in the field in Cameroon and produce data you can actually use.
Sensors & acquisition
Instrument selection and calibration matched to the parameter measured and the deployment context — power, dust, heat, connectivity.
Transmission
Data relayed by wired, radio, or cellular link depending on site constraints, with timestamped storage.
Dashboards & reports
Data delivered as a report or dashboard only where that deliverable is actually part of the engagement.
Maintenance & calibration
Periodic instrument checks and documented calibration to keep measurements reliable over time.
Data quality limits
Uncertainty, temporal coverage, and validity conditions for every measurement are stated explicitly, never glossed over.
A five-step method
The parameters, instruments, and exact deliverables are set per mission; the approach stays consistent.
Scoping
Understanding the issue, the site, and the decision the data needs to inform.
Measurement plan
Choosing parameters, measurement points, and a protocol matched to context.
Deployment & collection
Installing instruments on site and collecting data per the defined protocol.
Analysis & interpretation
Processing measured data and putting it in perspective against the original issue.
Report & recommendations
Clear reporting of results, their limits, and possible next steps.
Sectors we work with
Contexts where environmental data drives an operational or regulatory decision.
- Industry and impacted sites
- Mining, quarrying and construction
- Water and sanitation
- Healthcare, schools and public facilities
- Local government
- Development projects, NGOs and funders
