Overview
Totex, also identified in reference material as Totex Corporation, is a Japanese manufacturer of meteorological balloons. Its products are used in upper-air observation, where balloons carry radiosondes and related instruments into the atmosphere to collect information such as temperature, pressure, humidity, and wind conditions. The available reference material identifies balloon production as the company’s core business and records that production began in 1937. The company’s documented product family consists of three principal balloon types. TA is a rubber or latex balloon developed in 1940. CR is a chloroprene balloon introduced in 1966. TX is a latex balloon developed in 1988. These products represent successive material and product developments within Totex’s meteorological-balloon business. The TX model is identified as the standard used by Environment Canada in its upper-air program, linking Totex’s products to a national meteorological observation network outside Japan. Meteorological balloons are consumable or operational components of radiosonde systems rather than consumer products. They are launched from ground stations and rise through the atmosphere, carrying instruments that transmit measurements to receiving equipment. Their performance depends on material characteristics, manufacturing consistency, inflation behavior, lift, and the ability to operate through changing atmospheric conditions. Totex’s historical product range reflects the use of both latex-based and synthetic-rubber materials for this specialized application. Publicly available reference material is limited. It does not establish a current headquarters, ownership structure, parent company, executive roster, financial information, corporate website, or present operating status. It also does not provide a detailed account of the company’s commercial expansion, manufacturing facilities, distribution arrangements, or later product generations. Accordingly, Totex is best characterized on the available evidence as a specialized Japanese meteorological-equipment manufacturer whose documented identity is closely associated with sounding balloons and upper-air weather observation.
History
Totex’s documented history is centered on the production of meteorological balloons in Japan. The company began producing balloons in 1937, placing its origins in the early development of organized atmospheric sounding and balloon-supported weather observation. Meteorological balloons provide the lift needed to carry radiosondes and other instruments into the upper atmosphere, where measurements support weather forecasting, atmospheric research, and operational meteorological services. The reference record identifies 1940 as an important product-development date for Totex, when it developed the TA balloon. TA is described as a rubber or latex balloon, linking the company’s early product work to the elastic materials commonly used for sounding balloons. These balloons must combine low weight with reliable expansion and sufficient strength to ascend through the atmosphere. In 1966, Totex developed the CR balloon, made from chloroprene. The introduction of a chloroprene product marks a documented expansion beyond the company’s earlier rubber or latex formulation. Chloroprene is a synthetic-rubber material, and its use indicates continued attention to the material properties required for specialized meteorological applications. Totex’s next recorded product milestone came in 1988 with the development of the TX balloon, described as a latex balloon. The TX model subsequently achieved international operational relevance: the available reference material states that it became the standard used by Environment Canada in its Upper Air program. This association indicates that Totex products were used beyond the Japanese market in a formal national weather-observation context. Upper-air programs generally rely on balloon-borne radiosondes to gather atmospheric data used in forecasting and related scientific work. Beyond these product dates and the reference to Environment Canada, the supplied material does not document additional corporate milestones. There is no reliable information here about changes in ownership, corporate restructuring, facilities, senior management, financial performance, distribution partnerships, or the company’s current product portfolio. The available history therefore supports a concise account: Totex began balloon production in 1937, developed TA in 1940, introduced the chloroprene CR in 1966, and developed the latex TX in 1988, with TX later serving as a standard in Canada’s upper-air observation program.

Products and positioning
Specialist manufacturer of balloons for upper-air meteorological observation and radiosonde operations.
Meteorological balloon · 1940
TA
TA is a Totex rubber or latex meteorological balloon developed in 1940. It belongs to the company’s early documented product range and is designed for balloon-supported upper-air observation, in which the balloon carries a radiosonde or other atmospheric instrument package during ascent.
Chloroprene meteorological balloon · 1966
CR
CR is a chloroprene meteorological balloon developed by Totex in 1966. Its synthetic-rubber construction distinguishes it from the company’s latex-based products and reflects the use of alternative elastomer materials in specialized sounding-balloon manufacture.
Latex meteorological balloon · 1988
TX
TX is a latex meteorological balloon developed in 1988. The available reference material identifies it as the standard used by Environment Canada in its Upper Air program, giving the product a documented role in an international operational weather-observation system.
