Company scope
What the company makes
Ningbo Edeson Instrument Co., Ltd. (宁波艾德生仪器有限公司) builds equipment that simulates temperature, humidity, vibration and light. Its range covers temperature/humidity chambers, thermal-shock equipment, salt-spray testers, aging rooms and photovoltaic humidity-freeze chambers. A company article from May 2026 describes reliability testing for PV modules, connection parts and control equipment, and for energy-storage products.
For PV buyers the most concrete entry is the ETH-1000LA temperature and humidity chamber. Its detail table spans seven sizes from ETH-80L to ETH-1000L and five temperature options, and the figures were measured with no sample inside. Tell Edeson your sample, fixture and programme, and ask it to name the matching column and option.
Ningbo's 2024 third batch of science-and-technology SMEs includes the company under its Chinese name. The contact page gives an address in Jiangshan, Yinzhou, while the company introduction still names Dongqiao, Haishu. Ask which site builds, calibrates and services your chamber before you plan a visit or sign a contract.
Equipment portfolio
Start with the actual equipment
The entries below cover selected products and series from this manufacturer. Ask for the full catalogue if your project needs other models.
ETH-1000LA temperature and humidity test chamber →
The Edeson ETH-1000LA is a temperature and humidity test chamber for PV specimens, components and materials. Its catalogue table covers seven ETH sizes, with a 1000 mm cube inner box on the largest, and five temperature options reaching down to −70 °C.… [2]
Specifications & selection questions →Match the chamber to the job
Edeson chamber families and the job each one does
| Equipment family | Define for the quote | Ask Edeson |
|---|---|---|
| Temperature/humidity chamber | Temperature and humidity range, holds, transitions, sample loading and fixture | Which temperature and humidity combinations the chosen unit can hold at the same time. |
| PV humidity-freeze chambers | The exact programme and the chamber configuration you want | Whether the ETH-1000LA or a dedicated humidity-freeze unit should run your cycle. |
| Thermal-shock and rapid-temperature equipment | Transition speed you need and how the sample responds to it | The transition rate of the specific unit being quoted. |
| Aging rooms and ovens | Sample duty, any powered load, room size and controls | The rating for a powered heat load, and what a battery test would need. |
Each family is a separate purchase with its own specification sheet. [1][2][3]
Full modules need a fit check
Send real module dimensions, the fixture, clearances, orientation and sensor positions. The ETH-1000L column lists a 1000 × 1000 × 1000 mm inner box. Ask Edeson whether the ETH-1000LA uses the same box and whether your module fits once the fixture is in place. If you also test junction boxes or other connection parts, list their fixtures, since they share the chamber with module samples. [2]
ETH-1000LA and the shared table
ETH-1000LA figures and the conditions behind them
Five temperature options
The table offers options A to E, with lower limits from 0 °C down to −70 °C and a 150 °C upper limit. The page does not say which option the LA suffix stands for. Name the option you need in the enquiry and ask for a signed model sheet with the temperature and humidity envelope. [2]
Heating and cooling times
Heating from +25 °C to +85 °C takes about 25 minutes. Cooling from +25 °C to −40 °C takes about 55 minutes. Both times come from an empty chamber at +25 °C ambient and relative humidity ≤85%. Only the C, D and E options reach −40 °C at all. [2]
Fluctuation, deviation and display
Temperature fluctuation, humidity fluctuation, humidity deviation and display resolution sit on separate lines of the table. Each means something different. Ask Edeson for calibration, sensor locations, stable-hold results and loaded performance with your fixture and sample. [2]
Before you sign
Edeson's two addresses and the acceptance terms to agree
Settle which address applies
The contact page gives Building 25, Liandong U Valley, Heyicun, Jiangshan, Yinzhou. The company introduction names Dongqiao Industrial Zone, Haishu. Registration records show a Yinzhou registered address and older Dongqiao correspondence addresses. Ask Edeson where manufacturing, calibration and service take place today. [1][4]
Read the 2024 listing for what it is
The Ningbo attachment lists 宁波艾德生仪器有限公司 with entry number 2024330212A8006809. It is a dated company listing from that year. For chamber performance or accreditation, ask for test records on your configuration. The customers named in the introduction come from Edeson's own copy, so ask for contacts who bought a comparable chamber. [5][1]
Tie acceptance to your programme
Hand Edeson your test engineer's plan, the sample and the fixture. Ask for the model schedule, calibration records, loaded mapping, utility needs and agreed acceptance documents. The product table cites older standard editions, so ask Edeson which current PV qualification programme the chamber is built to run. Modules leaving a humidity programme usually go on to insulation and wet-leakage checks, so plan the electrical safety testing step at the same time. [2][3]
Project fit
Match the offering to your project
PV laboratories and component makers who already know the sample, fixture and test programme they need to run.
Buyers who compare chambers on loaded performance with their own sample instead of on nominal volume.
Confirm before ordering
- Which ETH table column and which temperature option the ETH-1000LA quote covers.
- Loaded performance with a PV specimen, the combined temperature/humidity envelope, and the current test programme the chamber is set up for.
- The manufacturing site, the contracting company and the test records supplied with your chamber.

Continue to sourcing requestBuyer questions
Will a full-size PV module fit inside the ETH-1000LA?
The ETH-1000L column lists a 1000 × 1000 × 1000 mm inner box. Edeson does not tie that column to the LA model by name, so send module and fixture dimensions and ask for the fit in writing. [2]
Does the −40 °C cooling time apply to every temperature option?
Options A and B stop short of −40 °C, so the figure only fits the colder options. It was also measured in an empty chamber. Ask for a loaded figure with your own sample. [2]
What does the 2024 government listing tell a buyer?
It names the company in Ningbo's 2024 list of science-and-technology SMEs. For the chamber itself, ask Edeson for a test report and calibration certificate on the configuration you order. [5]
Can I speak to Edeson's existing customers?
The company introduction names several customers. Ask Edeson for references who bought a comparable chamber for PV work and can describe how it performed. [1]
